Question

What ultimately leads to evolutionary change within a population?

पर्याय

• The immediate selection of all recessive alleles

• The physical adaptation of individual organisms during their lifetime

• The conversion of limiting factors into abundant resources

• Shifts in allele frequency within the population's overall gene pool

Answer 1

Selection pressure alters the gene pool by increasing or decreasing the spread of specific alleles. These shifts in allele frequency ultimately lead to evolutionary change.
