8.2 1 Gene Pools And Generic Diversity

Question 1

Population

Answer 1

Group of individuals of same species occupying a particular habitat and a particular niche within the habitat

Question 2

Gene pool

Answer 2

The sum total of all the alleles in a population at a given time
All about allele frequency

Question 3

Evolution

Answer 3

Involves a change in the allele frequency within a population

Question 4

P + Q= 1

Answer 4

P= frequency of dominant allele 
Q= frequency of recessive allele 

Limited as impossible to distinguish between homozygous dominants and heterzygotes

Question 5

The hardy - Weinberg equilibrium

Answer 5

In a population that is not evolving the allele frequencies of the population will remain stable from one generation to the next in the absence of other evolutionary influences

Question 6

Algebraic equation

Answer 6

p^2 + 2pq + q^2= 1

P^2= frequency of homozygous dominant genotype in a population 
2pq= frequency of heterozygous 
Q^2 = homozygous recessive 

BEACH

Question 7

Way to use measure

Answer 7

Measure q^2 then use p+q=1

Question 8

Equilibrium conditions

Answer 8

There are no mutations 
There is random mating 
The population is large 
The population is isolated 
There is no selection pressure - all genotypes are equally fertile /successful

Question 9

Mutations

Answer 9

Change in genetic material

Question 10

random mating

Answer 10

The likelihood of any two individuals in population will mate is independent to their genetic make up

Question 11

Hardy Weinberg equation

Answer 11

Only valid if it is applied to a large population as need random assortment of the alleles

Question 12

Isolation.

Answer 12

No migration of organisms either into or out of the population
Gene flow occurs

Question 13

Gene flow

Answer 13

The migration of either whole organisms or genetic material into or out of a population and into another population tending to make the populations more alike but changes in the allele frequencies all the time
