Question 2

Mutations

Answer 2

increase the gene pool of a population by increasing the number of different alleles available

Question 3

allele frequency

Answer 3

the relative frequency of a particular allele in a population

Question 4

if mutation results in an advantageous feature

Answer 4

will be selected and so there will be an increase in frequency

Question 5

more frequently is retained at a very low level

Question 6
