Chromosomes vs homologous chromosomes
WebAug 24, 2024 · The chromosomes can be of two types, homologous and heterologous chromosomes. The chromosomes that have similar gene sequences, chromosomal length, and centromere position are termed as homologous chromosomes whereas different chromosomes are termed as heterologous chromosomes.
