Students have asked these similar questions
a. What is the type of inheritance?
b. What is known of the genotype of the male in the above cross?

d. Provide map distances if possible.
The fetal DNA test has been shown to accurately predict all of the following except:

B. Diabetes
C. Trisomy 18
D. Down syndrome
In a paternity case a single mother claimed that a certain man was the father of her baby. The man denied it claiming that her current boyfriend was the father. The court ordered a blood test (cheaper than dna testing) to see if he could be ruled out as the father. The mother is type O and the baby was type O the man was type AB.
What is the possible genotype of the biological father?
A. Heterozygous Type A
B. Homozygous Type A
C. Heterozygous Type B
