Answers
The effect of nematode parasites on their host animals can vary depending on the specific species and the severity of the infection.
However, one common effect of nematodes, particularly those that reside in the gastrointestinal tract, is the loss of nutrients in the host animals.
Nematodes are known to feed on the nutrients present in the host's gastrointestinal tract, including carbohydrates, proteins, and other essential substances.
Thus, as a result, the infected host may experience a reduced ability to absorb and utilize these nutrients for their own growth and maintenance.

Answers
The grass blade from the mutant plant will appear unpigmented compared to that from the normal plant. So, option (d) is correct.
What is mutant plant ?
The look of a plant's traits, most notably its foliage, flowers, fruit, or stems, can change as a result of mutations in plants, a phenomenon that happens naturally. For instance, a flower might display two colors that are precisely half and half. Frequently, the mutant plants recover their normal state the following season.
What is unpigmented ?
Pigments are a group of chemical substances used to give other materials their color. They have a strong hue. These chromogens are also known as biological pigments or biochromes, which primarily refers to the actual pigments.
Vacuole help in the storage and disposal of various substances. They can store food or other nutrients required by a cell.
Lytic vacuoles function as reservoirs for ions and metabolites like pigments, acids, and toxic substances.
As the grass blade are made up of cells and in mutant plant there is no vacuole so storage of pigment will be not there.
Therefore, The grass blade from the mutant plant will appear unpigmented compared to that from the normal plant. So, option (d) is correct.

Explain why a somatic cell of Geneticus introductus has the same number of chromosomes and the same amount of DNADNA at the beginning of mitotic prophase as one of these cells does at the beginning of prophase I of meiosis.
Answers
Answer: Before mitosis and meiosis I, DNA is duplicated.
Explanation:
Cells go through a cell cycle from the time they are created until they die. This cycle has different stages or phases, known as G1, S, G2 and M. During G1, the cell prepares to divide, producing the proteins needed. After that, it enters the S phase, which is when the cell duplicates all its DNA. Then follows the G2 phase, it also prepares for cell division. Then follows the M phase, which is the division of the cell nucleus where the two copies of its genetic material that were created during the S phase are distributed, thus forming two genetically identical daughter cells in mitosis, which is the type of cell division that takes place on somatic cells.
Prophase is the first stage of mitosis, so when the cell enters this stage, it will have twice as much genetic material (which doubles during the S phase of the cell cycle). Also, an achromatic spindle is formed, the nuclear membrane disappears and the chromosomes condense. The next stage is metaphase, where the duplicated chromosomes line up in the center of the cell. Then during anaphase, the microtubules of the cell separate the chromosomes in opposite directions, towards the poles of the cell. Finally, during telophase, the nuclear membrane is re-formed and chromosomes are already in each newly formed daughter cell. So, now each daughter cell will have its own copy of genetic material, since it was duplicated during the S-phase.
For the formation of gametes, a similar process called meiosis occurs, consisting of meiosis I (chromosomes are separated) and meiosis II (sister chromatids of the same chromosome are separated). During the S phase, before meiosis I occurs, DNA is also duplicated. The process of meiosis is similar: prophase, metaphase, anaphase, telophase (the only difference is that during prophase, an exchange of genetic material occurs between the two homologous chromosomes). Then, at the end of meiosis I, two daughter cells are formed, each of which received half of the genetic material that was duplicated in the parent cell. This is the same amount of DNA that the daughter cells get during mitosis. During meiosis II, the sister chromatids are separated, forming two more daughter cells but they will have half of the genetic material, since there is no DNA duplication between meiosis I and II. So, this division is different. However, before mitosis and meiosis I, DNA duplication takes place.

Answers
The TYRTYR, TRP2TRP2, and TRP1TRP1 genes may be located on different chromosomes but are activated by the same transcription factor. Thus, the correct option is A.
What are Keratinocytes?Keratinocytes represent the major cell type of the epidermis layer of cells, the outermost layers of the skin, it has been found to making up to about 90 percent of the cells in the body. Keratinocytes originate in the deepest layer of the epidermis, the stratum basal and also move up to the final barrier layer of the skin, which is the stratum corneum.
The interaction of keratinocytes and the melanocyte cells is also crucial for the homeostasis of the epidermis layer of cells. Melanocytes are the cells which produce melanin pigment, which absorbs ultraviolet waves and prevents DNA damage to the keratinocytes. Keratinocytes do not produce melanin because these cells do not contain the TYRTYR, TRP2TRP2, and TRP1TRP1 genes.
Thus, the correct option is A.

Case Study
Jessie is a plant lover and is interested in growing grapes in her backyard. Based on her interest, she brought some seeds from a local store and grew it under all necessarily required conditions. She took good care of plant and allows it to fully develop its roots and stem. The temperature and moisture were also properly controlled during the growth but unfortunately, due to some reasons the grapes grown were not fleshy and had smaller size. It was also found that these grapes were less sweeter than the natural grapes. As she was concerned, she took her plant to the nearby agricultural research laboratory for proper investigation by Dr.Sean. Dr. Sean found 3 problems in this case and explained the cause of those problems to Marie and recommended suitable growth hormones to Marie.Identify the problems in this case and explain the cause of those problems. What could be the possible solution to these problems? Explain your answer in correct manner.
Answers
The problems in this Case Study of Jessie are:
Small size of the grapesLack of fleshiness in the grapesReduced sweetness of the grapesWhy the above problem?The causes of these problems could be due to various factors such as:
Improper pollination - Grapes require proper pollination to develop normally. If there is a lack of pollination or cross-pollination, the grapes may become smaller in size and less fleshy.Lack of proper nutrients - Grapes require proper nutrients such as nitrogen, phosphorus, and potassium to grow and develop properly. If the soil is lacking in these nutrients, the grapes may not develop properly.Lack of sunlight - Grapes require adequate sunlight for proper growth and development. If the plant does not receive enough sunlight, the grapes may become smaller and less sweet.To address these problems, Dr. Sean could recommend the following solutions:
Improve pollination - This could be done by introducing bees or other pollinators to the area. Additionally, planting other flowering plants in the area can also help attract pollinators.Provide proper nutrients - Dr. Sean could recommend adding fertilizers or other nutrients to the soil to ensure that the grapes receive the necessary nutrients.Therefore, In addition to these solutions, Dr. Sean may also recommend the use of growth hormones such as auxins or gibberellins to help stimulate growth and development of the grapes. Overall, proper care and attention, along with the recommended solutions, can help ensure the successful growth and development of the grape plant.

You are working with a population of snails. During the mating season, you observe that individuals in the population will only mate with others of the same genotype. For example, Mm individuals will only mate with Mm individuals, and mm individuals will only mate with other mm individuals. There are only two alleles for this gene (M is dominant; m is recessive). You have determined that the frequency of the M allele is 0.5. After one generation, what is the expected genotype frequency for Mm individuals in this population
Answers
If matings are not random in a population and individuals mate with other individuals of similar genotype/phenotype, h0m0zyg0us frequencies increase. In this example, the genotype frequency for Mm is F(Mm) = 0.25.
---------------------------------
In the exposed example, one of the assumptions of Hardy-Weinberg equilibrium is not accomplished. There are non random matings.
Individuals mate with other snails of the same genotypes
MM x MM
Mm x Mm
mm x mm
We can assume this is an example of matings by similar phenotypes.
Eventually, this mating system leads to an increase in the h0m0zyg0us genotype frequency, at the expense of heter0zyg0us ones in loci that determine the trait.
Allelic frequencies do not change. Only genotypic frequencies do.
This mating system tends to separate the population into two subgroups, decreasing the amount of heter0zyg0us individuals.
Matings Progeny
MM x MM 4/4 MMMM x Mm 1/4 MM + 2/4 Mm + 1/4 mmmm x mm 4/4 mmZygotic population of the next generation
F(MM) = 4/4 MM + 1/4 MmF(Mm) = 1/2 MmF(mm) = 4/4 mm + 1/4 MmSo, in the exposed example we know that the frequency of the dominant allele M is 0.5
f(M) = p = 0.5
knowing that p + q = 1, we can clear the equation to get the frequency of the recessive allele.
p + q = 1
0.5 + q = 1
q = 1 - 0.5
q = 0.5
f(m) = q = 0.5
Zygotic population of the next generation
F(MM) = 4/4 MM + 1/4 MmF(MM) = p² + 1/4 (2pq)
F (MM) = 0.5² + 1/4 (2 x 0.5 x 0.5) = 0.25 + 0.125
F(MM) = 0.375
F(Mm) = 1/2 MmF(Mm) = 1/2 (2pq)
F(Mm) = 1/2 (0.5)
F (Mm) = 0.25
F(mm) = 4/4 mm + 1/4 MmF(mm) = q² + 1/4 (2pq)
F(mm) = 0.5² + 1/4 (2 x 0.5 x 0.5) = 0.25 + 0.125
F(mm) = 0.375
The expected genotype frequency for Mm individuals in this population is F(Mm) = 0.25.
