However, a person with the O at the W gene has light body color O alleies at the H gene has lon hair. However, a cat with a dominant allele and a recessive genotype A8 has the blood type AB. A fly with a dominant allele at the S gene has short antennae, and a fly with a dominant allele and the W gene has short antennae and light body color A cat with two dominant alleles at the H gene has short hair, and a cat with two recessive allele at the H gene has short hair a fly with dominant alleles at both the S gene ?Previous ?Give Up & View Solution ?CNeck Answer·Next 2 Check Ananer Ntext Ex8Explanation / Answer
Answer: Option A is correct.
Explanation:
Epistasis: The interaction between alleles of two different genes.
BB = Black; GG = Gray; BBGG = Gray; it suggests that G is affecting the behavior of B. Hence it is an example of epistasis.
Blood groups in humans is an example of codominance. It does not involve epistasis. Hence option B is incorrect.
SS = short antennae; WW = light body color; SSWW = Short antennae and light body color; Here, there is no interaction between alleles of two different genes. Hence option C is incorrect.
H = Dominant allele = Short hair; h = Recessive allele = Long hair; Hh = Short hair. It is an example of complete dominance. Hence option D is incorrect.
