<h2>
The correct answer is explained below:</h2>
Explanation:
- According to the given question,
- For eye color, let the black color be represented by B allele and orange color be represented by b allele. Black is dominant over orange.
- For skin color, let the green skin be represented by G allele and white skin be represented by g allele. Green is dominant over white.
- The phenotype of Sam is black eyes and green skin so his genotype can be BBGG or BbGg. It is also said that one of his parents has phenotype orange eyes and white skin. That parent's genotype must be bbgg.
- Hence, the genotype of Sam must be BbGg.
- Carole has the phenotype of orange eyes and white skin. Her genotype would bbgg.
- The gametes produced by Sam are: BG, Bg, bG, bg.
- The gametes produced by Carole are: bg.
- Mating them we get,
BG Bg bG bg
bg BbGg Bbgg bbGg bbgg
(Black/ Green) (Black/ White) (Orange/Green) (Orange/ White)
- The genotypes and phenotypes (Eye color/ Skin color) obtained are represented above.
- The phenotypes (Eye color/ Skin color) obtained are in the following ratio:
(Black/ Green) : (Black/ White) : (Orange/Green) : (Orange/ White) = 1 : 1 : 1 : 1
Answer:
Somatic mutations : option (A) and option (D).
Inherited mutations : option (B) and option (C).
Explanation:
Mutations are permanent changes in the genetic material due to alterations in DNA sequence. Mutations may be somatic or inherited (or germline).
Somatic mutations are those mutations that arise in somatic or normal body cells and cannot transfer from parents to their offspring. As skins cells and lung cells are somatic cells, option (A) and (D) represent somatic mutations.
Inherited mutations are those mutations that arise in sex cells (gamete forming cell) and transfer from parents to their offspring due to transfer as these cells form mutated gametes. As egg cells and sperms cells are sex cells, option (B) and (C) represent inherited mutations.
Answer: acetyl group, methyl group, or phosphate group
