A single change or alteration in the nucleotide base of the genetic material of the cell is called a point mutation. It can be a deletion, addition or inversion of a single nucleotide base.
In the following, the mutations that occurred are 1. C and 2. B.
<h3>How the mutation can be explained?</h3>
- <u>Silent mutation</u> occurs in a single base of the triplet codons of the bases but the alterations do not cause an observable effect and they remain as a neutral alteration. They do not affect the function of the protein. Thus, the glycine to glycine is a silent mutation.
- <u>Non-sense mutations</u> are caused when the single change in the nucleotide base results in the formation of the stop codon. Thus, lysine to stop codon is a nonsense mutation.
Therefore, silent and nonsense mutations are the correct options.

The correct answer is option C
The frequency of the homozygous recessive genotype
In the Hardy-Weinberg equation, p is the frequency of the dominant allele, and q is the frequency of recessive allele then the frequency of genotype is represented by
p^2 = p x p = frequency of the homozygous dominant genotype ( AA)
q^2 = q x q = frequency of the homozygous dominant genotype (aa)
2 pq = p x q = The frequency of the heterozygous dominant genotype ( Aa)
The answer should be the first quarter moon
Answer:A population is a group of living organisms of the same kind living in the same place at the same time. All of the plant and animal populations living in a habitat interact and form a community. The community of living (biotic) things interacts with the nonliving (abiotic) world around it to form the ecosystem.
