State Hardy Weinberg's principle.

Text Solution

Verified by Experts

(i) The Hardy-Weinberg principle states that allele and genotype frequencies in a popula tion will remain constant from generation to generation in the absence of other evolutio nary influences.
`p^(2)+2pq+q^(2)=1`
`(p+q)^(2)=1`
(ii) It states that ontogeny recapitulates phylogeny. It means that embryos, in their development repeat the evolutionary history of their ancestors in a short, abbreviated form.
