Question 1

What is the foundation of population genetics?

Answer 1

Hardy-weinberg equilibrium

Question 2

What do phylogenetic trees allow us to do?

Answer 2

to organize the history of life on earth from its origins to viral pandemics

Question 3

What does population genetics help us tell about viruses?

Answer 3

predict the fate of variants

Question 4

What is the Hardy-Weinberg theorem steps?

Answer 4

A null hypothesis for population genetics
If rejected, then evolution has happened

Question 5

What is the purpose of the Hardy-Weinberg theorem?

Answer 5

-To detect evolution, try and reject the null hypothesis
-Assume the null hypothesis is correct, then you can use it to find the frequency of heterozygotes

Question 6

What does the Hardy-Weinberg theorem tell us?

Answer 6

the frequency of alleles and genotypes in a population will remain constant from generation to generation

Question 7

What is the formula for the Hardy-Weinberg theorem?

Answer 7

p^2+2pq+q^2=1

Question 8

What happens to the Hardy-Weinberg theorem if we observe no heterozygotes?

Answer 8

we reject the null hypothesis and predict that the heterozygotes die or come up with some sort of hypothesis to explain the fact that they are missing
