A gene showing codominance has

A gene showing codominance has

Options

  2. Balleles that are recessive to each other.
  3. Cboth alleles independently expressed in the heterozygote.
  4. Done allele dominant on the other.

Correct answer

C. both alleles independently expressed in the heterozygote.
