Populations (18)

Question 1

What is a species?

Answer 1

group of organisms that can be interbred to produce fertile offspring

Question 2

What is a gene pool?

Answer 2

all the alleles within a population

Question 3

What is a population?

Answer 3

all the organisms of a particular species that live in the same place

Question 4

What is allele frequency?

Answer 4

proportion of a certain allele within a gene pool

Question 5

How is allele frequency written?

Answer 5

either as a decimal or percentage

Question 6

What does the Hardy-Weinberg principle allow us to do?

Answer 6

allows us to estimate the frequency of alleles in a population, as well as if the allele frequency is changing over time

Question 7

What are the 5 assumptions that the Hardy-Weinberg principle makes?

Answer 7

1) no mutations occur to create new alleles
2) no migration in or out the population
3) no selection so alleles are all equally passed on to the next generation
4) random mating
5) large population

Question 8

What is the equation for allele frequency?

Answer 8

p + q = 1

Question 9

What is the equation for genotype frequency?

Answer 9

p2 + 2pq + q2 = 1

Question 10

What does p stand for?

Answer 10

dominant frequency

Question 11

What does q stand for?

Answer 11

recessive frequency

Question 12

What does p2 stand for?

Answer 12

frequency of homozygous dominant

Question 13

What does q2 stand for?

Answer 13

frequency of homozygous recessive

Question 14

What does 2pq stand for?

Answer 14

frequency of homozygous recessive
