Multiple Choice
Gia and Kojo collect a sample of beetles to calculate the frequency for the W allele. After genotyping the individuals in their sample, they count the following genotypes:
WW: 50
Ww: 170
ww: 120
Gia calculates the frequency by taking:
Kojo calculates the frequency by taking:
Who calculated the frequency incorrectly, and what was their mistake?
A
Kojo because he divided by the number of individuals instead of total alleles.
B
Kojo because he multiplied the number of homozygotes by 2 but not the number of heterozygotes.
C
Gia because she added instead of multiplying the number of W alleles found in the homozygote.
D
Gia because she did not multiply the total number of individuals by 2.
