Homework Answers
1. Migrate
Infinitely large
Randomly
are
2.Bottle neck effect: An example is the cheetah population
usually due to catastrophic event
loss of alleles can occur due to genetic drift
population size reduces to few individuals
results in loss of genetic diversity
Founders effect; small population increases probabily of losing alleles
usually due to geographic event
an example would be the old Order Amish
population started by a few members of another populatioon
results in loss of genetic diversity
3. A higher
4. Alters
dependent

5. Fur colour in mice is a single gene trait controled by two alleles. In a population of 75 mice, 21 are homozygous dominant, 37 are heterozygous dominant, and 17 are homozygous recessive. What is the frequency of the dominant allele in the population? Show all work and record your answer as a value between O and 1 rounded to two decimal places 6. The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the...

In the case of directional selection, if the advantageous allele (b) is recessive and a less advantageous allele (B) is dominant: A. b will be lost in the population because the dominant allele will increase in frequency by natural selection B. b will increase in frequency at the same speed as if it was a dominant advantageous allele, because what matters is the coefficient of selection and not if the allele is dominant or recessive C. b will increase in...
