Question

The Hardy-Weinberg principle states that evolution will not occur in a population when environmental conditions are stable. When there is a change in allele frequencies in a gene pool of a population, evolution has happened. Predict how two events—mutation and migration—will affect the Hardy-Weinberg principle.

Help my biology barely went over this in a class and now shes asking for a written question Dx

Answer 1

@R.Steelheart please

Answer 2

Let me see what I can do ok?

Answer 3

Is this Genetics?!

Answer 4

More like evolution

Answer 5

I'm taking both (sort of) next year..head start right?

Answer 6

aaaah i guess, whatever you can do just pleaaase try to answer if you can

Answer 7

I'm still working xD Sorry this is taking so long.

Answer 8

its okay whatever information you can scrape up will be fine :)

Answer 9

This might help a bit. http://www.course-notes.org/Biology/Outlines/Chapter_23_The_Evolution_of_Populations

Answer 10

Ah thank yoooou :D

Answer 11

Sorry I g2g, Sorry I can't help more

Answer 12

@lovely_horror The Hardy-Weinberg principle NEVER states that evolution will not occur. It states that the frequencies will be stable, given a list of factors are true. FYI these factor's are never true in real populations.

We have a population with a gene that has two alleles A and a. The frequencies are .75 for A and .25 of a. With the HW we know \[p^{2}+2pq+q^{2}=1\]We set p = freq of A and q = freq of a. If we have a mutation rate of 0.05% A to a for every generation, what will happen to the population frequencies over time? What if we have a migration of 0.05% of the population with A allele leaving every generation?
