Zoology - Evolution Question with Solution | TestHub
Which of the following is correct about Hardy Weinberg's principle?
Options:
Answer:
Solution:
Hardy was a mathematician and Weinberg was a physician. They devised Hardy- Weinberg principle. According to this principle, the allelic frequencies will remain constant in a population if there is no evolution taking place. In other words, if no evolution takes place the sum of allele frequency will always be equal to one. This is Hardy -Weinberg Equilibrium. Five factors are known to affect Hardy-Weinberg equilibrium. These are gene migration or gene flow, genetic drift, mutation, genetic recombination and natural selection. It is represented by the equation, whereis the proportion of pure homozygous dominant individuals in the population,is the proportion of pure homozygous recessive individuals in the population and 2pq is the proportion of heterozygous individuals in the population.
