An individual with a heterozygous genotype is a:
Correct answer: A. Heterozygote
- A. Heterozygote
- B. Homozygote
- C. Both A & B
- D. None of the above
Explanation
Option A: Heterozygote refers to an individual who has two different alleles for a particular gene, meaning they have a heterozygous genotype. In this case, the individual has inherited one allele from each parent, resulting in a heterozygous genotype. Option B: A homozygous refers to an individual who has two identical alleles for a particular gene, meaning they have a homozygous genotype. This option is incorrect for a heterozygous genotype since it implies having two identical alleles rather than two different alleles. Option C: This option would indicate that an individual with a heterozygous genotype can be both a heterozygote and a homozygote, which is not accurate. A heterozygous genotype specifically represents the condition of being a heterozygote, not a homozygote.

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.
