2. STATEMENT:
A woman and man both do not have sickle-cell anemia, but both had one parent who
had sickle cell. Sickle-cell is an autosomal (somatic) recessive trait.
a) What is the genotype for the woman, man and each of their parents?
b) This couple unexpectedly is going to have their first child.
i.
What's the probability that their child will have not have sickle cell like the couple?
ii.
What's the probability that the child will have sickle cell like one the grandparents?
A man with hemophilia (X-linked recessive) has two kids:
a girl who has a normal phenotype, and
a boy who has hemophilia.
What is the genotype of the man?
What is the genotype of the boy?
From which parent did the boy
get his X-chromosome?
What is the genotype of the girl?
• What must be the genotype of their mother?
If this same man and woman have more children,
what are the chances that a son will be affected?
A2.Q what diagnosis would you give patient A? I want to make sure if I'm right and if I'm wrong where did I mess up
I said trisomy 13 syndrome
