Evolution takes place on the (a)   level.

4.

A population is said to be in H-W equilibrium IF:

(select ALL that apply)

a)

allele frequencies are constant from one generation to the next

b)

all 5 H-W conditions are met

c)

at least 3 of the 5 H-W conditions are met

a)

0.002

b)

0.9553

c)

0.0447

0.890

b)

0.943

c)

0.332

d)

8.

In a population of newts, producing toxin is a recessive trait, while not producing toxin is dominant.

In this population of newts, 387 / 587 newts do not produce toxin. What is the frequency of newts that are heterozygous in the population?

Round to the hundredths place.

9.

small population size

b)

No natural selection

c)

Gene flow

d)

Nonrandom mating

e)

Mutations

10.

The purpose of the Hardy-Weinberg equilibrium theory is to use math to demonstrate whether or not evolution is occurring by measuring (a)   frequencies over several generations.
