Answer:
Due to the industrial revolution, smoke caused the environment of the peppered moths to change to a darker/black color. This resulted in a higher prevalence of black peppered moths over white peppered moths.
Explanation:
The dark environment made it so black peppered moths had the favorable trait while the white moths, who previously had the advantageous trait due to old environments being light in color, now had a deletirous trait. Predators could now more easily see the light colored moths, so they were more likely to be killed than the dark colored moths, so more dark colored moths were able to reproduce. This lead to a larger prevalence of dark peppered moths.

Answer:
0.42
Explanation:
Since 70% of the gametes have an A1 allele, this means that the frequency of the A1 allele in the population is 70% or 0.7.
The population is in Hardy-Weinberg equilibrium. For this population, the frequency of another allele for the same locus (A2) would be= 1- frequency of A1 allele = 1-0.7 = 0.3
The proportion of flies carrying both A1 and A2 alleles would be = 2 x frequency of A1 allele x frequency of A2 allele.
So, frequency of heterozygous flies= 2 x 0.7 x 0.3 = 0.42 or 42%
Answer:
1/3
Explanation:
The first thing to do is to figure out all possibilities.
I'll use f for female and m for male.
The possible outcomes are: 5f, 4f 1m, 3f 2m, 2f 3m, 1f 4m, or 5m.
Since there are 6 possible outcomes, and 2 of the outcomes are 2 males and 3 females or 3 males and 2 females, the probability is 2/6 or 1/3!
