The English moth, Biston betularia, is often cited as an example of observed evolution. There are two colors of this moth, light

and
dark (typica and carbonaria). Kettlewell found that dark moths constituted less than 2% of the population prior to 1848. Then, the
frequency of the dark coloration began to increase. By 1898, the 95% of the moths in Manchester and other highly industrialized
areas were of the dark color. Using the moth example, analyze the events in order to identify support for the statement: natural
selection changes populations, not individuals. Choose ALL that apply.
A)
Variation in the population existed.
B)
Color variation is a result of different gene combinations.
In response to environmental change, moth coloration changed from light
to dark.
D)
Due to natural selection, the ratio of different genetic combinations is
changing
E)
Predator pressure resulted in the light colored genotype being removed
from the gene pool.

You are studying a population of snapdragon plants on Membata Island. In snapdragons, the dominant allele CR encodes red flowers
fredd [130]

Answer:

we will know that the allelic frequencies are for R 0.95 and r 0.05

Explanation:

We know that the population is in Hardy-Winberg equilibrium, we deduce the following formula:

p + q = 1

p2 + 2pq + q2 = 1

data

R: red flower allele

r: allele blor blanca

p would be equal to the allelic frequency R

q will be equal to the frequency allelic r

2p = RR

2q = rr

2pq = Rr

If there are 25 white flowers in 1000 plants, their frequency will be:

2pq frequency of the Rr genotype

white flower = 25/10000 = 0.0025 = rr = 2q = 0.0025

we deduce that q is equal to 0.05

we replace the data with the previous formula

p + q = 1

p = 1-0.05

we get as a result

  p = 0.95

if p = 0.95 and q = 0.05

we will know that the allelic frequencies are for R 0.95 and r 0.05
