I just want someone to look over my answers to make sure I am calculating correctly.  I am using the Hardy-Weinberg Equlibrium to figure out the answers to the questions.

 

Thank you,

Question 2
Calculate the genotypic and allele frequencies with a given population.
47 individuals (13 BB, 23 Bb, 11 bb)
a. What is the frequency of homozygous dominant individuals?
b. What is the frequency of homozygous recessive individuals?
c. What is the frequency of heterozygous individuals?
d. How many alleles are in the population?
e. What is the frequency of the dominant allele?
f. What is the frequency of the recessive allele?
Answers:
a. (13BB/47 individuals) : 0.28
b. (23BB/47 individuals) : 0.49
c. (11bb/47 individuals) : 0.23
d. 2 Alleles: Bb
e. ((13+11/2)/47): 0.25
f. ((23+50/2)/47): 0.75
Notes: a, b, c totaled together = 1
e and f totaled together = 1
