Solved by a verified expert:1)Joe’s grandfather (on his mothers side) was a lizard man
on a circus sideshow (the result of rare
X-linked recessive allele that gave him a tail). Joe meets and marries Julie,
whose uncle on her mothers side had a tail removed at the age of 2. Julie is now pregnant with their first child
1)
Assign genotypes.
2)
What is the probability that their first child
will have a tail?
3)
If the first child does have a tail, what is the
probability that a second child will have a tail?
2) Achondroplasia (dwarfism) is an autosomal dominant
disorder, where individuals homozygous for the mutant allele do not survive
1) if a woman with
achondroplasia marries a man of normal height, what
proportion of their offspring is expected have achondroplasia?
2) if a woman with
achrondroplasia marries a man with achondroplasia , what proportion of their
offspring is expected to have achondroplasia?
