According to the figure below, the r allele is less frequent in generation II of this flower population. The frequency of r decreases in this population because
A)of genetic drift.
B)recessive alleles are always less common than dominant alleles.
C)p + q must always equal 1.

Quizplus · Accepted Answer

The frequency of the r allele decreases due to genetic drift, which is the random fluctuation of allele frequencies in a population. This can occur due to chance events such as natural disasters, founder effects, or bottlenecks, which can reduce genetic variation and cause certain alleles to become more or less frequent over time.

According to the Figure Below, the R Allele Is Less
