sources of variation Flashcards
1
Q
Gene pool
A
the gene pool is the total sum of alleles available in a population
2
Q
Allele frequency
A
allele frequency is the number of times an allele occurs in a population
3
Q
Continuous variation
A
a complete range of measurements from one extreme to another eg height
4
Q
discontinuous variation
A
when characteristics fall into a category eg earlobes
5
Q
Genetic biodiversity
A
range of different genes and alleles present in the gene pool (the greater number of different alleles = the greater genetic bio diversity)
6
Q
Mutation
A
a mutation is a permanent/ random change in the DNA nucleotide sequence
