HH = 25 Hh = 150 hh = 225

Calculate the frequencies of the H and h alleles. If these minnows were allowed to randomly mate and produced a population of 2000 individuals, how many minnows of each genotype do you expect to find in the offspring (assuming equal survivorship)?

Thank you for the opportunity to help you with your question!

We have

Genotype frquency:-

HH ,p^2=25/(25+150+225)=25/400 =.0625

hh ,q^2=225/(25+150+225)=.5625

Hh,2pq =150/(25+225+150)=.375

Now,frequecny of H=p^2+1/2*2pq =.0625+.375/2 =.25

frequency of h=q^2+1/2*2pq =.5625+.375/2 =.75

Expected genotype frequency:

HH=.25^2 =.0625

hh=.75^2 =.5625


Expected number of individual of each genotype

HH:.0625*2000 =125

Hh=.375*2000 =750
