Cat fur color is determined by codominance. The allele for tan fur (T) and the allele for black fur (B) are codominant. The heterozygous condition (TB) results in a cat with tan and black spots, called a tabby cat.
What would the probable phenotypic ratio of the offspring be, if two tabby cats mated?

A--- 100% Tan

B-- 75% Tabby 25% Black

C-- 25% Tan 50% Tabby 25% Black

D-- 75% Tan 25% Tabby

The probable phenotypic ratio of the offspring be if two tabby cats mated - C-- 25% Tan 50% Tabby 25% Black

Codominance is a pattern of inheritance in which two different alleles are both expressed in a heterozygous individual, but the resulting phenotype is not a blend of the effects of each allele.

  • Cat fur color is determined by codominance.
  • The allele for tan fur (T) and the allele for black fur (B) are codominant.
  • The heterozygous condition (TB), called a tabby cat, results in a cat with tan and black spots.

cross: Ff x Ff

     F    f

F   FF  Ff

f  Ff    ff

here the genotypic ratio - 1 FF: 2 Ff; 1 ff

and, phenotypic ratio - 1 Black: 2 Tabby: 1 Tan

Thus, the probable phenotypic ratio of the offspring be if two tabby cats mated - C-- 25% Tan 50% Tabby 25% Black
