The phenotype of individuals heterozygous for ________ alleles comprises both homozygous phenotypes.

  1. a. epistatic
  2. b. codominant
  3. c. pleiotropic
  4. d. hybrid

Summary Introduction

Concept introduction: Alleles do not follow the laws of Mendelian inheritance. Some alleles, such as codominant alleles do not follow the pattern of Mendelian inheritance. Codominance refers to codominant alleles where neither masks the effect of the other and both the products are expressed in heterozygous condition.

Explanation of Solution

Reasons for correct statement:

Codominant alleles do not have any dominant or recessive condition. When both the alleles occur together in heterozygous condition, the products of both the alleles are expressed and the phenotype expresses both the alleles. For example, ABO blood group. When IA allele and IB allele are expressed as heterozygous alleles, the blood group is AB.

Option b. is given as “codominant”.

Since codominant alleles when expressed in heterozygous condition express the phenotype of both the alleles in the individual, option b. is correct.

Reasons for the incorrect statements:

Option a. is given as “epistatic”...
