7. In horses coat color shows incomplete dominance: the alleles are chestnut color
(Hc) and cremello (Hcr); heterozygous individuals have the phenotype palamino.
What are the predicted phenotypes from a cross between a palamino and cremello.
colored horses? What are the genotypes?
And what is the Punnett square for that cross?
Answers
The phenotype of palomino in horses is a result of incomplete dominance between chestnut color (Hc) and cremello (Hcr) alleles. Heterozygous individuals have a palomino phenotype.
Therefore, the genotype of palomino horse can be represented as HcHcr.
A cross between a palomino (HcHcr) and cremello (HcrHcr) colored horses can be represented as:
Hc Hcr
Hc | HcHc HcHcr
Hcr| HcHcr HcrHcr
The predicted phenotypes of the offspring would be 50% palomino (HcHcr) and 50% cremello (HcrHcr).
The genotypes of the offspring can be determined by analyzing the Punnett square. The square indicates that 25% of the offspring will inherit a chestnut color allele from the palomino parent and a cremello allele from the cremello parent, resulting in HcHcr genotype.
Another 25% will inherit two copies of the cremello allele, resulting in HcrHcr genotype. The remaining 50% of the offspring will inherit a chestnut color allele from one parent and a cremello allele from the other, resulting in HcHcr genotype.
Therefore, the cross between a palomino and cremello colored horses will result in offspring with both palomino and cremello phenotypes in a 1:1 ratio, and the genotypic ratio will be 1:2:1 for HcHc:HcHcr:HcrHcr.

Sometimes, a mother who is affected with a mitochondrial disease will have an unaffected child. Which of the following could explain this observation?
A. The phenotype could be affected by nuclear genes, which could differ among children.
B. Environmental factors (such as taking antibiotics) could affect expression of the phenotype.
C. The affected mother could be heteroplasmic.
D. One or more of the children could inherit the majority of their mitochondria from an unaffected father.
Answers
C. The affected mother could be heteroblastic . The chance of producing an unaffected child increases if the egg has a higher proportion of normal DNA.
What is Phenotype?
Phenotype refers to the observable physical, biochemical, and behavioral characteristics of an organism, which are determined by the interaction of its genotype (genetic makeup) with the environment. It is the expression of the genes of an individual, which can be influenced by various factors such as the individual's developmental history, environmental factors, and lifestyle.
Mitochondrial diseases are caused by mutations in mitochondrial DNA ( DNA). Inheritance of DNA follows a maternal pattern, meaning that the DNA is passed down from the mother to her offspring. In some cases, a mother who has a mitochondrial disease may have some unaffected children. One possible explanation for this is that the mother is heteroblastic, meaning that she has a mixture of normal and mutant DNA in her cells. When she produces eggs, the distribution of normal and mutant DNA in each egg can vary, and this can result in some eggs having predominantly normal DNA, while others have predominantly mutant DNA.

Asexual reproduction is capable of producing many copies of a single genotype over a short period of time. How is this an advantage in parasitic taxa?
Answers
Answer:
Explanation:
Asexual reproduction (also called asexual multiplication) corresponds to the ability to live organisms to multiply alone (without male or female partners), that is to say without involving the fusion of two gametes of different sex.
The parasitic organism usually hinges on their host cells for nutritional benefits and for sustenance. Before this can happen, they need to adjust to the new environment(i.e. the host cell environment) and alter the functionality of the host immune system.
Hence, by using asexual means of reproduction, newer species which have genetically and environmentally hybrid species are being produced which can quickly adapt to these environments and they can thrive better than their predecessors.

A small forest stood on the edge of an expanding city. In the middle of the forest was a large pond, which arose from a natural spring. As the city expanded, the forest was cut down, the pond drained, and the area paved over for a mall and office buildings. After five years, the average humidity of the area seemed to have decreased. Use your knowledge of the water cycle to interpret this observation.
Answers
Explanation:
The water cycle ( aka the hydrological cycle ) is a biogeochemical cycle which illustrates the constant movement of water on, above and below the Earth's surface.
The water cycle plays a major function in the sustainability of life on Earth as most living organisms can't do without water. Because the cycle is a natural process, it depends on natural presences for its continuation and those presences certainly do not include office buildings and malls.
Plants contribute majorly to the water cycle, as do animals, but not on such a large scale as plants. Green plants give off water in its gaseous state (water vapour) through the process of transpiration which is one of the key stages in the water cycle. Green plants also absorb and make use of the water in the earth's soil which is made possible through the process of percolation, another key component of the hydrological cycle.
For the scenario stated in the question, because the trees which made up the forest were cut down to give way for the city's expansion, there was an alteration in that region's water cycle. The pond which was sustaining and being sustained by their roles in the efficient circulation of water, naturally began to dry up with their decreasing numbers.
Thus, the humidity of the area ultimately decreased with time because of this alteration.

Which condition causes transpiration to INCREASE?
lower humidity
no air movement
colder temperatures
high soll moisture
Answers
High soil moisture causes transpiration to increase by increasing the water potential of the plant, increasing the relative humidity of the atmosphere, and increasing the turgor pressure of the plant cells. Here high soil moisture is the correct answer.
Transpiration is the loss of water vapour from the surfaces of a plant or a leaf. A condition that causes transpiration to increase is high soil moisture. Plants get water from the soil through their roots. High soil moisture increases the water content of the soil and the water potential of the plant. The water potential of the plant is the measure of the pressure required to extract water from the plant. High soil moisture reduces the water potential gradient between the soil and the plant.
The high soil moisture creates a favourable condition for transpiration because it increases the relative humidity of the atmosphere around the plant. Transpiration occurs because the air surrounding the leaf is drier than the air inside the leaf. When the relative humidity of the atmosphere is high, the rate of transpiration increases.
The high soil moisture also increases the turgor pressure of the plant cells. Turgor pressure is the pressure that water exerts on the cell wall of the plant. The turgor pressure is what keeps the plant cells rigid. When the turgor pressure is high, the rate of transpiration increases. Therefore high soil moisture is the correct answer.

The first cell cycle pause (G1) corresponds to typical cell growth and function.
The G1 phase is the initial gap phase. It is the interphase stage just before DNA replication. In the S phase, which follows the G1 phase, the cell replicates its DNA.
The cell physically expands during the G 1 start subscript 1, end subscript phase, also known as the first gap phase, duplicates organelles and produces the molecular building blocks required for subsequent processes.

What are the unique characteristics of the garden pea that allowed George Mendel (the father of genetics) to study them successfully?
Answers
Mendel chose the pea, one of many species, to study because the plants and seeds exhibit a variety of distinctive characteristics that appear in two readily recognizable forms (e.g., seed shape is round or wrinkled; plant height is tall or short).
George Mendel, the father of genetics, chose pea plants for his genetic experiments for a variety of reasons, including
• Garden plants are simple to grow.
• Pea plant blooms are hermaphrodites, which means they exhibit traits of both sexes.
• Plants of the pure breed can be easily obtained through self-fertilization.
• Pea plants produce more quickly than other plants.
• They have a high rate of survival and remarkable disease resistance.
Gregor Mendel's research on pea plants led him to the fundamental ideas of inheritance. He came to the idea that genes are passed down from each parent as unique, paired units.
Mendel observed how parental genes separated and if they showed up as dominant or recessive qualities in the offspring. Gregor Mendel experimented with hybridization on about 29,000 pea plants. Mendel found that peas were the perfect subject since they possessed seven easily observable features that he could control. He set up two settings before starting his pea studies.
As a result, we can infer that Mendel chose the pea as the species to study out of all the others since it has a diversity of distinguishing traits in both its plants and seeds.
