An individual carrying two different alleles of a gene, such as Tt, is described as
Correct answer: C. heterozygous
- 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.

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
