Question 1

Inbreeding depression, the reduction in fitness of inbred organisms, often results from the reduced level of what (within the gene pool)?

Accepted Answer

genetic he

Question 2

What are the two most common types of nonrandom mating?

Accepted Answer

inbreeding

Question 3

In an island population, the frequencies of the three MN blood types are given here:
M: 550
MN: 725
N: 225
a. Calculate the allele frequency of M and N.
b. Assuming random mating, what are the expected frequencies for each blood type?
c. Use chi-square analysis to test your hypothesis that mating is random for this population.

Accepted Answer

a. p = f (M)= [2(550)+ 725]/3000 = 0.608

Question 4

If the frequency of hemophilia, an X-linked recessive disease, is 10% in males, what is the frequency of carriers in the population (both males and females)?

Accepted Answer

0% of male

Question 5

Accepted Answer

A) 0.022% 
B) 98.5% 
C) 2.9% 
D) 1.49% 
E) 2.2% 
A) 0.022% 
B) 98.5% 
C) 2.9% 
D) 1.49% 
E) 2.2%

Question 6

You want to calculate the frequency of the allele causing sickle cell disease in your patients, and you know the genotypes of every individual. Assuming the population is not in Hardy-Weinberg equilibrium due to population substructure, which method can be used to calculate allele frequency?

Accepted Answer

A) allele-counting method 
B) genotype proportion method 
C) square root method 
D) binomial expansion 
E) chi-square test

Question 7

What are the three key elements for determining F, a measure that a particular allele is IBD, using pedigree analysis?

Accepted Answer

The three key elements to determining F
