You are studying natural selection in a population of small marine invertebrates called isopods that live on pink corals. In this population, isopod body color is controlled by one gene with alternate alleles A and a. Isopods can be red (AA), pink (Aa), or white (aa); body size is controlled by another gene with alternate alleles B and b, and they can be large (BB or Bb) or small (bb). A new predator arrives on the reef that is extremely good at preying on isopods that are large and stand out against the corals on which they live (i.e., red or white individuals). Over time, which genetic individuals would you predict would become more abundant in the population with each subsequent generation?

Answers

Answer 1

Answer:

Aa, bb

Explanation:

Recall that this question calls our attention to the theory of evolution as postulated by Charles Darwin. Species that are well adapted to their environment are more likely to survive, reproduce and pass on these favourable characteristics to their offspring.

In this case, the coral reefs are pink and pink Isopod species with small bodies are likely to escape the predators. Hence the genetic combination Aa(pink body) and bb(small body) are more likely to survive and reproduce.

How do the differences in the DNA bases affect the amino acid sequence of both people?

Answers

The differences in the DNA bases between individuals can affect the amino acid sequence of the proteins they produce. The DNA sequence is translated into a sequence of amino acids through the process of protein synthesis. The DNA sequence is read in groups of three nucleotides, called codons, and each codon corresponds to a specific amino acid.

There are four different nucleotide bases in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). The sequence of these bases determines the sequence of the codons in the DNA, and therefore the sequence of the amino acids in the resulting protein.

A change in a single base pair can result in a different amino acid being added to the growing protein chain. This is called a "missense" mutation. Alternatively, a change in a single base pair can result in a premature stop codon, which can lead to a truncated protein or a non-functional protein. This is called a "nonsense" mutation.

The differences in the DNA bases between individuals can result in different amino acid sequences and different protein structures, which can have a range of effects on an individual's traits and susceptibility to disease. For example, some genetic diseases are caused by mutations in specific genes that result in abnormal proteins. Understanding the effects of these mutations on protein structure and function can provide insight into the underlying mechanisms of these diseases and inform the development of potential treatments.

What characteristic do you have that you hope to pass on to your progeny? Why?

Answers

Characteristics found in germ lines are generally passed down to the next generation of offspring through sexual reproduction, whereas traits found in somatic cells are not.

What is the significance of the passing of traits?

Traits, also known as characteristics, are generally passed on to the next generation as they are present on germ line cells, such that in the case of the male, they produce sperm so, the active genes on the sperm will express in the offspring, and in the case of the female, the active gene on the ovum will express in child.

Hence, characteristics found in germ lines are generally passed down to the next generation of offspring through sexual reproduction, whereas traits found in somatic cells are not.

what is mutation ? explain types and significance

Answers

Mutation:

Mutation is a change in the genetic material (DNA) of an organism. These changes occur spontaneously or can be induced by mutagens such as radiation, chemicals, and viruses. Mutations can occur in any organism, including plants, animals, and humans.

Types of mutations:

Point mutations: These involve a change in a single base pair of DNA. There are three types of point mutations: substitution, insertion, and deletion. Substitution is the replacement of one nucleotide with another, while insertion and deletion are the addition or loss of one or more nucleotides.

Chromosomal mutations: These involve changes in the structure or number of chromosomes. Examples include deletion, duplication, inversion, translocation, and nondisjunction.

Gene mutations: These are changes that occur within a gene, resulting in altered or nonfunctional proteins. Gene mutations can be caused by point mutations, chromosomal mutations, or changes in regulatory sequences.

Significance of mutations:

Evolution: Mutations are the basis of genetic variation, which is essential for evolution. Mutations provide the raw material for natural selection to act upon.

Disease: Mutations can cause diseases by disrupting normal gene function. Some genetic disorders, such as sickle cell anemia and cystic fibrosis, are caused by mutations.

Biotechnology: Mutations can be used in biotechnology to produce genetically modified organisms with desirable traits, such as disease resistance or increased yield.

Cancer: Mutations can cause cancer by altering the function of genes that regulate cell growth and division. Some mutations can also affect DNA repair mechanisms, increasing the likelihood of further mutations.

In conclusion, mutations can have a significant impact on the organism and the environment. While some mutations can be harmful, others can be beneficial and drive evolutionary change. Understanding mutations and their effects is essential for fields such as biotechnology and medicine.

Answer:

Mutation is a genetic term that refers to a change in the DNA sequence of an organism's genome.

Some types of Mutations are point mutations, frameshift mutations and chromosomal mutations
Mutations are significant because they provide genetic diversity, can confer adaptive advantages, cause genetic disorders and diseases, and play a critical role in the process of evolution.

Explanation:

Mutation is a genetic term that refers to a change in the DNA sequence of an organism's genome. Mutations can occur naturally or be induced by external factors such as radiation or chemicals. They can be harmful, beneficial, or neutral depending on the specific change and the effect it has on the organism. Mutations can occur in many different ways, such as substitutions, insertions, deletions, duplication, and inversion. While many mutations are neutral or harmful, some mutations can provide an advantage to an organism in certain environments, leading to evolutionary changes over time.

There are several types of mutations that can occur in an organism's DNA sequence. The most common types include

Point mutations, which involve changes to a single nucleotide, and can be further categorized as silent, missense, or nonsense mutations.

Frameshift mutations involve the insertion or deletion of nucleotides, which alters the reading frame of codons and can result in a completely different protein being synthesized.

Chromosomal mutations involve changes to the structure or number of chromosomes and include deletions, duplications, inversions, and translocations.

Mutations are significant for several reasons:

Genetic diversity: Mutations are the ultimate source of genetic diversity, which is necessary for evolution to occur. They introduce new alleles into a population, which can be selected for or against depending on their fitness.

Adaptation: Mutations can provide organisms with adaptive advantages in changing environments. For example, mutations in bacteria can confer resistance to antibiotics, allowing them to survive in antibiotic-treated environments.

Disease: Mutations can also cause genetic disorders and diseases. For example, mutations in the BRCA1 or BRCA2 genes increase the risk of breast and ovarian cancer.

Evolution: Mutations play a critical role in the process of evolution by introducing new genetic variations that can be selected for or against based on their fitness.

In summary, mutations are significant because they provide genetic diversity, can confer adaptive advantages, cause genetic disorders and diseases, and play a critical role in the process of evolution.
