Question

What is it called when two homologous chromosomes code for different alleles?

Answer 1

Heterozygous for gene:

1. Heterozygous for a gene refers to when a homologous set of chromosomes has different alleles of the same gene.
2. The 22 homologous autosomal chromosomes in humans have the similar genes but code for different characteristics in their allelic forms, because one was inherited from the female parent and the other from the father.
3. Heterozygous for a gene refers to when a homologous pair of chromosomes has different alleles of the same gene. A gene pair's two alleles are found on homologous chromosomes.
4. Alleles are a type of gene that differs from others.
