Leto [7]

Answer:

For black:

  • AABB
  • AaBB
  • AaBb
  • AABb

For brown:

  • AAbb
  • Aabb

For golden:

  • aaBB
  • aaBb

Explanation:

This question explains the phenomenon of epistasis. Epistasis encompasses the concept where one gene is dominant in such a way that it completely masks the effect of any other gene present. Here, black is said to be the epistatic gene considering the abundance in its appearance. The ratio of 9:3:4 can be seen in cross 8 which makes this question an example of recessive epistasis. Recessive epistasis occurs when alleles of one locus mask the appearance of alleles, both dominant and recessive, on the other locus. Recessive epistasis is also known as supplementary epistasis.
