Question

What are the homologous and heterologous portions of the human sex chromosomes?

Answer 1

$hello mate$

The homologous portion of human sex chromosomes is the part which contains genes with alleles in both the Y and X sex chromosomes. The homologous portions are mostly located in the central part of the sex chromosomes, near the centromere.

The heterologous portion of human chromosomes is the part whose genes do not have corresponding alleles in the other sex chromosome. These genes are mostly located in the peripheral regions of the arms of the Y and X chromosomes.

Answer 2

A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosome that pair up with each other inside a cell during meiosis



Heterologous chromosomesare the chromosomes that differ in type, function, or size. Example are X and Ychromosomes.
