Populations

Question 1

Define species

Answer 1

A group of organisms that can interbreed
to produce fertile offspring

Question 2

Define population.

Answer 2

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

Question 3

Define gene pool

Answer 3

The range of different alleles existing for
a particular locus within a population

Question 4

Define allele frequency

Answer 4

The proportion of a certain allele within a
gene pool, expressed as a decimal or
percentage

Question 5

What is the Hardy-Weinberg principle?

Answer 5

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

Question 6

Give the assumptions made by the
Hardy-Weinberg principle

Answer 6

● No mutations occur to create new alleles.
● No migration in or out of the population.
● No selection, so alleles are all equally passed
on to the next generation.
● Random mating.
● Large population
