Natural Selection Is More Complicated Than I Thought

Question 1

Directional

Answer 1

One end of distribution curve is fitter than the others

Question 2

Stabilizing

Answer 2

The middle ones are more fit than the others

Question 3

Disruptive

Answer 3

Lower and upper end is more fit than the middle

Question 4

Bottleneck effect

Answer 4

Dramatic reduction in population size

Question 5

Founder effect

Answer 5

Happens when small subgroup of population migrates to a new place

Question 6

Nonrandom mating

Answer 6

Females prefer fitter males

Question 7

Small populations are prone to genetic drift because?

Answer 7

Small gene pool

Question 8

Gene flow

Answer 8

Movement of genes in or out of population

Question 9

Two effects of genetic drift are

Answer 9

Bottleneck effect and founder effect

Question 10

Hardy Weinberg principle has what five things

Answer 10

Nonrandom mating

Small populations are prone to genetic drift

Gene flow

Mutations

Natural selection

Question 11

What causes directional selection

Answer 11

A phenotype at one end is favored

Question 12

What causes stabilizing selection

Answer 12

Intermediate phenotype under selection and extremes will have less success

Question 13

What causes disruptive selection

Answer 13

When extremes of a phenotype are favored

Question 14

Speciation

Answer 14

Making of new species

Question 15

Reproductive isolation

Answer 15

Separation of a species so they can’t reproduce anymore

Question 16

Reproductive isolation can have three different types

Answer 16

Behavioral isolation
Geographic isolation
Temporal isolation

Question 17

Behavioral isolation

Answer 17

Two populations reproduce differently so they don’t wanna mate with each other

Question 18

Geographic isolation

Answer 18

Two populations are separated because of land stuff like rivers and mountains

Question 19

Temporal Isolating

Answer 19

Two species reproduce at different times so they don’t mate with each other
