What happens when a section of a population migrates to a new location according to the paragraph?
Options
- AGene frequencies remain unchanged
- BGene frequencies in both the original and new populations change
- CThe original population becomes extinct
- DNew genes are introduced but the old population remains unaffected
Correct answer
B. Gene frequencies in both the original and new populations change
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 occur
