Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

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 or gametes formation.
when meiosis occur after the fussion of gametes or before the fussion?
you know meiosis is complete in two sussessive division that is meiosis 1st and 2nd. in the meiosis 1st homologous chromosomes are segrigate. then in the meiosis 2nd sister chromatids are segrigate like that mitosis
meiosis is occur before the fusion of gametes
after gametes fusion mitosis is occur. bcz after gametes fusion a diploid cell is form. but before gametes fusion the gamete is haploid.
