Fruit colour in squash is an example of:
Options
(a) Recessive epistasis
(b) Dominant epistasis
(c) Complementary genes
(d) Inhibitory genes
Correct Answer:
Dominant epistasis
Explanation:
Epistasis is the phenomenon of suppression of phenotypic expression of gene by a nonallelic gene which shows its own effect. A dominant epistatic allele suppresses the expression of a nonallelic gene whether the latter is dominant or recessive. For example , fruit colour of Summer squash (Cucurbita pepo) is governed by a gene which produces yellow colour in dominant state (Y-) and green colour in recessive state (yy).
