1. In a population of 200 field mice, 98 mice are homozygous dominant for brown fur (FF), 84 mice are heterozygous (Ff), and 18
iVinArrow [24]
A.
The genotype frequencies can be determined by dividing the number of individuals with a genotype by the total number all the individuals. 
FF genotype frequency:
98÷200=0,49. There are approximately 5 <span>homozygous dominant mice in 10.
Ff genotype frequency:
84</span>÷200=0,42. There are approximately 4 <span>heterozygous mice in 10.
ff genotype frequency:
18</span>÷200=0,09. There are approximately 1 <span>homozygous recessive mouse in 10.

B.
To determine the frequency of an allele we can divide the number of times that the allele appears by the total number of alleles.
F allele frequency:
</span>\frac{(98*2)+84}{400}<span>=0.7
There are 7 F alleles in 10 random alleles.
f </span>allele frequency:
\frac{84+(18*2)}{400}=0.3
There are 3 f alleles in 10 random alleles.<span>
