22. Evolution of Populations

When all the alleles in a population are considered together, independently of the individuals they come from, we call that the ___________.

Which of the following terms is correctly matched to its definition?

The number of individuals in a population with each of the following genotypes is listed below. What is the frequency of the small t allele?

TT: 640

Tt: 200

tt: 160

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: $W=\frac{50+50+170}{680}$

Kojo calculates the frequency by taking: $W=\frac{2\left(50\right)+170}{50+170+120}$

Who calculated the frequency incorrectly, and what was their mistake?
