If the frequency of an allele is 0.75, how many copies of this allele should be in a population of 300 diploid individuals?
Ray Of Light [21]

I have provided the options below:

a. 150

b. 225

c. 300

d. 450

e. 75

Answer:

150

Explanation:

Hardy-Weinberg law states, the allelic frequencies of a gene that is, q and p follow the relationship p^2+q^2+2pq = 1, if the population is in equilibrium.

Therefore p^2+q^2+2pq = 1, can be used to calculate the percentage of the allelic frequencies i.e. p^2 and q^2

Allelic frequency = 0.75.

Therefore, the percentage of the allele in the population would be given by

0.75^2 = 0.5625 = 56%.

And the total number of individuals with this allele in the population:

number of individuals = 56×300÷100

= 168 or

150 nearest figure.

What factor controlled the population of peppered moths in england?
Molodets [167]
The evolution of the peppered moth evolutionary  instance of directional colour change in the moth population as a consequence of air pollution during the Industrial revolution .The frequency of dark-coloured moths increased at that time, an example of industrial mellaniam. Later, when pollution was reduced, the light-coloured form again predominated. Industrial melanism in the peppered moth  was an early test of Charles Darwin natural selection  in action, and remains as a classic example in the teaching of evolution.

Helpppp pleaseeeeeee
JulijaS [17]
75% purp, 25% white i would think. you could easily eliminate the 50% purp 50% white because that wouldn’t make sense, purp is the dominate color. it would most likely not be 100% purple because there are two 25-75 answers, which would most likely make it one of those answers. since purp is the dominate color, 75% white would not make sense, making the correct answer 75% purp and 25% white.
