Solutions

Expert Solution

Homolog--- if the genes have similar sequences in 2 different species are result of common genetic ancestors , those genes are known as homologs or homologous genes.

Homologous pair -- homologous chromosomes are homologous pair which carry same genes, same length , same centromere position , have same banding pattern. They are composed of one maternal chromosome and one paternal chromosome.
