Which Hardy-Weinberg equation represents the genotype frequencies in a population?

p + q = 1

p2 + 2pq + q2 = 1

p2 + pq2 + q2 = 1

p + 2pq + q3 = 1

Which Hardy-Weinberg factor represents the frequency of heterozygous individuals in a population?

2pq

p2 + 2pq

What do you call all of the genes in a population?

Gene pool

Relative Frequency

Genetic Drift

Allele pool

A few deer wander out of their native woods into a completely new park where no deer had ever been before. They go on to create an entirely new population.

Genetic Drift

Natural Selection

Non-random mating

Mutation

Genetic drift is likely to be seen in a population

That has a low mutation rate

In which natural selection is occurring

That is very small

For which environmental conditions are changing

In the Hardy-Weinberg Equation, q² is the frequency of what?

The recessive allele

the dominant allele

the recessive genotype

the dominant genotype

The Hardy-Weinberg Model is...

available at local hobby stores and retailers throughout the Greater Tazewell area.

a mathematical tool that biologists can use to predict allele frequencies and determine whether or not evolution is occurring within a population.

always occurring within individual organisms in nature.

only useful in the lab and cannot be practically applied to real-world populations of organisms.

A population of 150 individuals has an allele frequency of 0.3 for the dominant allele (B) and a frequency of 0.7 for the recessive allele (b). Use the Hardy-Weinberg equation to determine the frequency of the genotype (bb).
