How do losses of alleles in natural selection differ from losses of alleles in genetic drift?
A - In natural selection, alleles are lost if they do not confer a survival advantage, whereas in genetic drift alleles are lost if they do not confer an advantage in partner selection
B - In genetic drift. alleles are lost if they do not confer a survival advantage, whereas in natural selection alleles are lost if they do not confer an advantage in partner selection
C - In genetic drift, alleles are lost if they do not confer a survival advantage, whereas in natural selection the losses are random
D - In natural selection, alleles are lost if they do not confer a survival advantage, whereas in genetic drift the losses are random
Answer: D - In natural selection, alleles are lost if they do not confer a survival advantage, whereas in genetic drift the losses are random
GENETIC DRIFT is the random loss of individuals and the alleles they possess. This is why the populations need to be big, the bigger they are the more they can absorb the random loss of alleles without significant effect to the gene pool.
