What happens when both alleles of a gene pair independently express in a heterozygote?
Correct answer: D. Codominance
- A. Dominance
- B. Incomplete dominance
- C. Over dominance
- D. Codominance
Explanation
Codominance, as it relates to genetics, refers to a type of inheritance in which two versions (alleles) of the same gene are expressed separately to yield different traits in an individual.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
