What differences Mendel identified between parent and F2 generation.
Answers
Answer:
Mendel observed various differences between the parent generation and the F2 generation( obtained by self-pollination of the F1 generation progenies) which are given below:
1. While the parent generation contained all pure breeds, the F2 generation contained mixed breeds.
2. Parent generation had only homozygous set of gametes whereas F2 generation had a mixture of homozygous as well as heterozygous gametes.
3. The set of characters are fixed in parent generation but in the case of the F2 generation, new combinations are observed.
Answer:
The whole chain of breed starts with parental generation while F2 generation is the end result of this chain.
Explanation:
The parental generation P is the first of parents crossed. F2 Generation consists of the offsprings from allowing F1 generation to interbreed while F1 generation is a result of Parental generation.
Parent generation consists of pure breed whereas F2 generation contains mixed breeds because it is the second filial generation of cross breed. Parental generation involves homozygous sets of gametes while F2 generation contains a mixture of both homozygous and heterozygous gametes. This is the reason that leads to the third difference which is that the set of characters are not fixed in F2 generation but in parental generation they are fixed.
