Question

explain the law of segregation with example

Answer 1

First recorded in 1940–45.Also called Mendel's first law, Mendel's law.parent may have two distinct alleles for a certain gene, each on one copy of a given chromosome. Mendel's second law, the law of segregation, states that these two alleles will be separated from each other during meiosis. Specifically, in the second of the two cell divisions of meiosis the two copies of each chromosome will be separated from each other, causing the two distinct alleles located on those chromosomes to segregate from one another.

Answer 2

Mendel's law of Segregation (or Law of purity of gametes) :

The two alleles of a gene when present together in a hetero-zygote state, do not fuse or blend in anyway, but remain distinct and segregate during meiosis or in the formation of gametes so that each meiotic product or gamete will carry only one of them.

This law is based on the fact that the alleles do not show any blending and that both the characters are recovered as such in the F₂ generation though one of these is not seen at the F₁ stage.

Segregation of genes is a universal phenomenon in all organisms reproducing by normal sexual method.
