Am I doing these right? Really struggling with allele frequencies and genetics in general. Please help?

Can you transfer into the class of a teacher whose first language is English?
Start by eliminating B because evolution does not explain the origin of life. That also eliminates choice D.
Look at the table. You have 200+250+50=500 individuals. They have 2*500 = 1000 alleles.
There are 200+200+250=650 B alleles.
There are 250+50+50=350 b alleles.
51. Genotypic frequencies are:
BB: 200/500 = 0.4
Bb: 250/500 = 0.5
bb: 50/500= 0.1
52. Phenotypic frequencies are:
We have no way of knowing since your teacher did not say anything about the phenotypes. Your teacher sucks. Let's assume that B is dominant; b is recessive; that BB and Bb are "brown fur color"; and that bb is "white fur color." Repeating for emphasis: Your teacher sucks.
Brown fur color: (200+250)/500 = 0.9
White fur color: 50/500 = 0.1
53. let p = freq(B) = 650/1000 = 0.65
54. let q = freq(b) = 350/1000 = 0.35
55. 1000 total alleles at this gene locus
