STEPS
1.Find the given allele. q2=44% (homozygous recessive individual)
2.Convert percentage into a decimal. 44%=.44
3.Square root .44 to find q. √.44=.66 (recessive allele)
4.Use the equation 1-q=p to determine p. 1-.66=.34 (dominant allele)
5.Multiply square .34 to find p2. p2=.11 (homozygous dominant individual)
6.Substitute p and q in the equation 2pq. 2(.34)(.66)=.45 (heterozygous individual)
7.Check answer by using p+q=1 and p2+q2+2pq=1. .34+.66=1 .11+.45+.44=1
8.Multiply all 3 genotypes by 1000 to find the number of individuals of each genotype.
44% x 1000 = 440 11% x 1000 = 110 45% x 1000 = 450
ANSWER
440 homozygous recessive individuals
110 homozygous dominant individuals
450 heterozygous individuals
