Question 1 as reference 1. In a population of 1000 bison, there are two alleles at the B locus. It acts incompletely dominantly,so that you are able to figure out each animal's genotype simply by observing its phenotype. Howconvenient.You find 665 BB, 225 Bb, and 110 bb bison.Total population= 1000So genotypic frequency of BB= 665/1000 =0.665Genotypic frequency of BB= 225/1000 =0.225Genotypic frequency of bb= 110/1000 =0.11a)What are the allele frequencies of B and b? (round off the number)The gene or allele frequency of B would be = 0.665+ (0.225/2) =0.78The gene or allele frequency of b would be = 0.11 + (0.225/2) =0.22Using the allele frequencies, what numbers (not just fractions, but numbers of actual bison inthis population of 1000 and yes you can round off) would you expect to be BB, Bb, and bb?b)we have got the allele frequency of B & b.So the expected number of genotype would be =(0.78+0.22)² =(0.78)²+ 2×0.78×0.22 +(0.22)? =0.61+0.34+0.05|BB would be =0.61 ×1000= 610Bb would be =0.34 ×1000= 340bb would be =0.05 ×1000= 50с)Do you think this bison population is in HW equilibrium?The observed and expected frequency of genotypes are not exactly same.

Question

Question 1 as reference

1. In a population of 1000 bison, there are two alleles at the B locus. It acts incompletely dominantly,
so that you are able to figure out each animal's genotype simply by observing its phenotype. How
convenient.
You find 665 BB, 225 Bb, and 110 bb bison.
Total population= 1000
So genotypic frequency of BB= 665/1000 =0.665
Genotypic frequency of BB= 225/1000 =0.225
Genotypic frequency of bb= 110/1000 =0.11
a)
What are the allele frequencies of B and b? (round off the number)
The gene or allele frequency of B would be = 0.665+ (0.225/2) =0.78
The gene or allele frequency of b would be = 0.11 + (0.225/2) =0.22
Using the allele frequencies, what numbers (not just fractions, but numbers of actual bison in
this population of 1000 and yes you can round off) would you expect to be BB, Bb, and bb?
b)
we have got the allele frequency of B & b.
So the expected number of genotype would be =(0.78+0.22)² =(0.78)²+ 2×0.78×0.22 +
(0.22)? =0.61+0.34+0.05|
BB would be =0.61 ×1000= 610
Bb would be =0.34 ×1000= 340
bb would be =0.05 ×1000= 50
с)
Do you think this bison population is in HW equilibrium?
The observed and expected frequency of genotypes are not exactly same. So this population is not in
Hardy Weinberg equilibrium.
d)
No matter what your answer to c, if they weren't in HW equilibrium, name 5 possible reasons
why.
Ansuer this..

2.
In a similar population of 1000 bison (but one with different allele frequencies than the one in
question #1), which you AREALRX KNOW is in HW equilibrium, there are 160 bb bison. What are
the allele frequencies of B and b?
Ansuer this...

6. You have identified an autosomal gene that contributesto tail size in male guppies, with a dominant allele B forlarge tails and a recessive allele b for small tails. Femaleguppies of all genotypes have similar tail sizes. Youknow that female guppies usually mate with males withthe largest tails, but the effects of population densityand the ratio of the sexes on this preference have notbeen studied. You therefore place an equal number ofmales in three tanks. In tank 1, the number of femalesis twice the number of males. In tank 2, the numbers ofmales and females are equal. In tank 3, half as manyfemales as males are present. After mating, you findthe following proportions of small-tailed males amongthe progeny: tank 1, 16%; tank 2, 25%; tank 3, 30%.a. In your original population (before the animals wereplaced in the three tanks), 25% of the males havesmall tails.
