Which of the following is dominant epistasis?
Albinism in humans
Coat color in mice
Flower color in snapdragons
Eye color in fruit flies
Flower color in snapdragons is a dominant epistasis example. The expression of two genes determines the color of the flowers, with one gene controlling the production of a pigment precursor and the other gene controlling the conversion of the precursor into pigment.The expression of the second gene is masked by the dominant allele at the first gene resulting in a novel phenotype. Hence option C is the correct answer.
Option(A) Albinism in humans is a genetic disorder. Hence option A is incorrect.
Option(B) Coat color in mice is a mendelian character. Hence option B is incorrect.
Option(D) Eye color in fruit flies is a sex linked inheritance. Hence option D is incorrect.
