Industrial revolution is when people started making a bunch of factories.

It affected the color of dark colored moths because they were able to camouflage into their environment better because of the soot from the factories, therefore increasing the number of dark moths that survived in their environment over light colored moths.

Natural selection is when the environment and environmental factors affect an organisms ability to survive and reproduce in that environment, causing only the most fit organisms to be able to survive and reproduce.

There is a population where the frequencies of allele 1 and allele 2 are 0.7 and 0.3, respectively. Allele 1 has a selection coe
Lorico [155]

Answer:

0.8

Explanation:

There is a population where the frequencies of allele 1 and allele 2 are 0.7 and 0.3, respectively

Let's use GG to represent allele 1

Let's use gg to represent allele 2

So we can equally say that;

GG = p = 0.7

gg = q  = 0.3   ( from Hardy-Weinberg Equilibrium)

So, given that the selection coefficient = 0.2

We known that the cross between GG and gg will definitely results to (GG,Gg and gg)

Then the fitness of these genes can be represented as:

1 - s, 1 and 1 - t respectively.

Thus. the allele 1's genotype fitness can be determined as

= 1 - s    ( where s is the selection coefficient)

= 1 - 0.2

= 0.8

eduard

Answer: C) The event at the end of the Triassic Resulted in the extinction of fewer fauna’s then in any other period

Explanation:

Looking at the graph, the event at the end of the Triassic resulted in the smallest dip in the amount of fauna in the graph. This means that this event resulted in the extinction of fewer faunas than any of the other five major events.

Option A is wrong as the event at the end of the Devonian decreased the number of Cambrian fauna.

Option B is wrong as the event at the end of the Cretaceous resulted in a decrease in the Paleozoic fauna.

Option D is wrong because the event that resulted in the Extinction of more fauna’s then in any other period was the event at the end of the Permian.
