<h3>The somatic and sex chromosomes mainly differ in their Ploidy.</h3>
- Somatic Chromosomes are Diploid (2n)
- Sex Chromosomes are Haploid (n)
Haploidity of sex chromosomes enables the formation of a diploid zygote after fertilization
<h3>Somatic Chromosomes are homologous in nature while the Sex Chromosomes can be Analogous as in the case of Spermatozoa which bears XY genes </h3>
