What is the basis of this law regarding alleles?

Options

  1. AAlleles blend together
  2. BAlleles do not show any blending
  3. CAlleles mutate frequently
  4. DAlleles disappear in the F1 generation

Correct answer

B. Alleles do not show any blending

Step-by-step solution

This law is based on the fact that the alleles do not show any blending and that both the characters are recovered as such in the F2 generation though one of these is not seen at the F1 stage. Though the parents contain two alleles during gamete formation, the factors or alleles of a pair segregate from each other such that a gamete receives only one of the two factors. Of course, a homozygous parent produces all gametes that are similar while a heterozygous one produces two kinds of gametes each having one allele
