Question

Descendants that have a common ancestral DNA or protein sequence but have undergone significant divergences while still retaining some similarity are said to be homologous. This term is widely used in evolutionary biology to describe relationships among organisms based on similarities and differences in their genetic makeup. Heterologous refers to unrelated sequences, analogous refers to structures or functions that have evolved independently in different organisms, heterozygous describes individuals with different alleles at a given genetic locus, and homozygous describes individuals with two identical alleles at a given genetic locus.
