Imagine a population of 100 annual wildflowers, some red and some yellow. The red allele, R, is domi

Hello guys, I need help with this question!

Microevolution is the change of frequencies of alleles in the gene pool. Imagine a
population of 100 annual wildflowers, some red and some yellow. The red allele, R, is
dominant; the yellow allele, r, is recessive. There are 36 RR plants in the population,
48 Rr plants, and 16 rr (yellow) plants.

a) What are the genotype frequencies for the current generation?

b) What are the frequencies of R and r alleles in the gene pool?

c) Use the rule of multiplication to calculate the frequencies of the three possible genotypes
of plants in the second generation.

d) What are the frequencies of R and r alleles in the gene pool for the second generation
(assuming the population stays at 100 individuals)?

e) What happened to the genotype and allele frequencies in the second generation? What
would you predict for the third generation? Why?
