Read the following statements and choose the following option: 1. When migration of a section of population to another place and population occurs, gene frequencies change in the original as well as in the new population 2. There would be a gene flow if this gene migration, happens multiple times. 3. There would be a genetic drift if this gene migration, happens by chance 4. Natural selection is a process in which he
Options
- A1, 2 and 5 are correct
- BBoth 1 and 2 are incorrect
- CBoth 3 and 5 are correct
- DOnly 4 is incorrect
Correct answer
A. 1, 2 and 5 are correct
Step-by-step solution
Five factors are known to affect Hardy-Weinberg equilibrium. These are gene migration or gene flow, genetic drift, mutation, genetic recombination and natural selection. When migration of a section of population to another place and population occurs, gene frequencies change in the original as well as in the new population. New genes/alleles are added to the new population and these are lost from the old population. There would be a gene flow if this gene migration, happens multiple times. If the same change occurs
