Hardy-Weinberg Principle

Question 1

What is evolution

Answer 1

The change in inherited characteristics of a group of organisms over time due to changes in the frequency of different alleles within the population

Question 2

What is allele frequency

Answer 2

Relative frequency of a particular allele in a population

Question 3

What is the Hardy-Weinberg Principle

Answer 3

In a stable population with no disturbing factors the allele frequency will remain constant from one generation to the next and there will be no evolution

Question 4

Five assumptions of the Hardy-Weinberg Principle

Answer 4

-no mutations(no new alleles created)
-no immigration/emigrations means no new alleles introduced/lost
-no selection pressures- no alleles favoured/eliminated
-mating random=alleles mixed randomly
-population large = no genetic bottlenecks( gene pool getting narrower)

Question 5

Predicting allele frequency equation

Answer 5

p + q = 1
p(dominant allele)
q(recessive allele)

Question 6

Predicting genotype frequency equation

Answer 6

p2 + 2pq + q2 = 1
p2( homozygous dominant)
2pq (heterozygotes)
q2 (homozygous recessive)

Question 7

What is the gene pool

Answer 7

Sum of all the genes in a population at any given time
