An allosome is a sex chromosome that differs in size, form and behaviour from an autosome. Humans have one pair of allosomes These chromosomes contain genes that determine the biological sex of an organism.

Answer:
The pair of autosomes are homologous in humans. Female allosomes are homologous while male allosomes are non-homologous. The number of genes varies from 200 to 2000. Y chromosome contains a few genes but X chromosome contains more than 300 genes.
