- A couple, who are both normal, have a daughter who is albino and a son who is normal. a) what is the probability that their normal son is a carrier of the albinism gene? Show your work. b) the couple wants to have 3 more children; what is the probability that they will have 3 normal girls? Show your work.A young couple went to see a genetic counselor because each had a sibling affected with cystic fibrosis. (Cystic fibrosis is a recessive disease and neither member of the couple nor any of their four parents is affected). What is the probability that the female of this couple is a carrier and what are the chances that their child will be affected with cystic fibrosis?Why do unrelated children with a disorder such as Down syndrome resemble each other more closely than they do their siblings?
- what is the probability that a couple (both heterozygous for the same recessive mutation) will have two children with the disease if the couple plans to have four children in total?Johnny has unattached earlobes (a dominant trait) like his father, but his mother has attached earlobes. What is johnny’s genotype?Mr. and Mrs. Jones have six children. Three of them have attached earlobes (recessive) like their father, and the other three have free earlobes like their mother.
