Answer 2

a group of organisms of the same species occupying a particular space at a particular time that can potentially interbreed

Question 3

what is a gene pool?

Answer 3

• all the alleles in a population

Question 4

what is allele frequency?

Answer 4

• proportion of a certain allele in a gene pool

Question 5

why is Hardy-Weinberg’s equation used?

Answer 5

• to estimate the frequency of alleles in a population

Question 6

what the assumptions made before using Hardy-Weinberg’s equation?

Answer 6

• no mutations have occurred to create new alleles
• no movement of alleles into or out of population due to migration
• population is large
• no selection = every allele has an equal chance of being passed to the next gen
• mating is random
