Multiple choice

The inheritance of Epistatic Genes followed Mendel's law of independent assortment because:

  1. the first two classes of this have merged to produce a single phenotype

  2. there is interaction of two non allelic dominant genes

  3. the F1 phenotype is the same as that of true breeding dominant variety

  4. the F1 produces four kind of gametes in equal proportion
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Epistatic genes follow Mendel's law of independent assortment because the F1 hybrid produces four types of gametes in equal proportions (AB, Ab, aB, ab) even though phenotypic ratios may be modified by gene interactions. This maintains the fundamental principle of independent segregation.
