Chapter 17 Population genetics: mutation, genetic drift ,

Question 1

Genetic drift

Answer 1

random changes in allele frequencies due to sampling error across generations
- Drift reduces genetic diversity

Question 2

where does sampling error occur

Answer 2

much stronger in smaller populations

Question 3

Extreme types of drift

Answer 3

Founder effect and Bottleneck

Question 4

Founder effect

Answer 4

genetic variation in population will reflect that from the starting population

Question 5

Bottleneck effect

Answer 5

genetic variation is reduced due to dramatic decrease in population size

Question 6

Calculating Hardy Weinberg effect fir alleles

Answer 6

homozygous recessive/dominant + 1/2 of heterozygous.
