An individual carrying two different alleles of a gene, such as Tt, is described as
- A. homozygous dominant
- B. homozygous recessive
- C. heterozygous
- D. hemizygous
Explanation
Heterozygous means two unlike alleles at a locus, and such individuals are often called carriers when the recessive allele is hidden. Hemizygous is a different state, having only one copy of a gene, as with X linked genes in males.
