A) Darwins theory
B) Lamarcks theory
C) Hardy-Weinberg principle
D) de Vries theory
Correct Answer: C
Solution :
The Hardy-Weinberg (G H Hardy and G Weinberg; 1908) law states that the gene and genotypic frequencies in a Mendelian population remain constant generation after generation if there is no election, mutation, migration or random drift. Hardy-Weinberg used the binomial expression, \[{{p}^{2}}+2pq+{{q}^{2}}\]where \[{{p}^{2}}=%\] homozygous dominant individuals p = frequency of dominant allele \[{{q}^{2}}=%\] homozygous recessive individuals q = frequency of recessive allele. 2pq = % heterozygous individuals. To calculate the genotypic and allele frequencies of a population. Hardy-Weinberg principle gives the geneticists a tool to determine, when evolution is occurring. Population geneticists use Hardy-Weinberg principle to calculate a starting point allele frequency and then compare it to frequencies measured at some future time.You need to login to perform this action.
