7.2 Population

Question 1

What is a population?

Answer 1

All of the individuals of one species living in an area

Question 2

What is a species?

Answer 2

Organisms that can interbreed to produce fertile offspring

Question 3

What is the gene pool?

Answer 3

All of the alleles in a population

Question 4

What assumptions does the hardy-Weinberg principle assume?

Answer 4

The assumptions are:
No mutations, migration or emigration.
No selective pressure for or against a specific genotype.
Population size is infinite.

Question 5

What are the two important hardy-Weinberg equations?

Answer 5

• p^2+2pq + q^2 = 1
  p2 = pp = homozygous dominant.
  q2 = qq = homozygous recessive.
  2pq = heterozygous.
• p+q=1
  p = frequency of one allele.
  q = frequency of other allele.
