What might this suggest regarding how exactly gamma rays interact with DNA?

Question 1 (10 points)
Show that the the E-gene in turkeys is located on the Z-chromosome. Use the Rich Text Editor to create two Punnet squares of reciprocal crosses as your evidence.

Question 3 (10 points)
In terms of the Orange gene in felines, which term mentioned earlier in the course best describes how the O0 and OB alleles are related to one another?
Question 3 options:
co-dominance
mosaic
polymorphism
mutant
Question 4 (10 points)
There is an autosomal gene in cats that controls whether or not they also have white patches of fur (W = white spots, w= no white spots). Considering this along with the Orange gene (O0 and OB) from the previous question, and how it works, how many possible genotypes (using these 4 alleles) are there for cats that are orange, black, and white (in other words, calico)?
one
two
three
four
Question 5 (10 points)
Determine the most likely mode of inheritance for the following pedigree:
Question 5 options:
autosomal dominant
X-linked dominant
autosomal recessive
X-linked recessive
Question 6 (10 points)
If Subject 1 in the pedigree shown below is heterozygous for a rare autosomal recessive disease, what is the likelihood that Subject 7 will inherit the disease?
Question 6 options:
1/2
1/4
1/8
1/16
1/32
1/64
0
Question 7 (10 points)
Researchers sometimes use gamma rays to induce deletion mutations in certain organisms and thus create mutant strains. What might this suggest regarding how exactly gamma rays interact with DNA? What are they probably causing to happen that results in these deletion mutations?
Question 8 (10 points)
Explain, in detail, how you could use the FISH method to to determine whether a person is 47,XYY male or 47,XXX female.
Question 9 (10 points)
How many of the following people would have cells containing ONE Barr Body?
46,XY
46,XX
47,XYY
47,XXX
45,X
47,XXY
Question 9 options:
zero
four
three
six
five
two
one
Question 10 (10 points)
What would be the result from a nondisjunction of chromosome 21 in a zygote that is 46,XY? Explain your answer.
