Question

Why law of segregation is also called the law of purity of gametes?

Answer 1

1. A diploid organism contains two factors for each trait in its diploid cells and the factors segregate during the formation of gametes.
2. The two alleles (contrasting characters) do not mix, alter or dilute each other and the gametes formed are ‘pure’ for the characters which they carry.
3. A gamete may carry either a dominant or recessive factor but not both.

Hence, this law is also called the law of purity of gametes.
