Question

What idea did Hardy and Weinberg disprove?

Answer 1

They disproved the idea that dominant alleles' percentages will rise throughout generations, which causes recessive alleles' percentages to sink.

Explanation:

The Hardy-Weinberg equation is

`p^2+2pq+q^2=1`

where

`p` is the frequency of allele A

`q` is the frequency of allele a

`p^2` is the frequency of individuals with AA

`2pq` is the frequency of individuals with Aa

`q^2` is the frequency of individuals with aa

It means that without an external factor (like mutation or gene flow), the allele frequencies will most likely remain unchanged throughout generations. This is because natural selection only depends on the organism's phenotype and not genotype.
