Evolution takes place on the (a) level.
A population is said to be in H-W equilibrium IF:
(select ALL that apply)
allele frequencies are constant from one generation to the next
all 5 H-W conditions are met
at least 3 of the 5 H-W conditions are met
allele frequencies change from one generation to the next
If a recessive disorder is found to affect 1 in 500 live births, what is the frequency of the dominant allele?
0.002
0.9553
0.0447
0.9125
If the frequency of the homozygous dominant genotype is 0.36, what is the frequency of the dominant allele?
0.2
0.48
0.6
0.8
In a population of sandworms, 89% of individuals have small eyes (aa) and 11% of the population have large eyes. What is the frequency of the recessive allele in this population?
0.890
0.943
0.332
0.057
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.
Which of these is a condition that must be met for Hardy-Weinberg equilibrium?
small population size
No natural selection
Gene flow
Nonrandom mating
Mutations
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.
