Huntington's disease is caused by a dominant allele. What are the chances of having a child that will develop Huntington's disease if one of the parents has Huntington's
Added by Austin C.
Step 1
Step 1: When one parent has Huntington's disease, they will pass on the dominant allele for the disease to their child. Show more…

Huntington's disease is caused by the allele H, which is completely dominant to the normal recessive allele h. Consider a couple where the man has the genotype Hh, and the woman has the genotype hh. What is the chance that their first child will develop Huntington's disease? 0% 25% 50% 75% 100%

Huntington's disease is an autosomal dominant disorder, which means that a person needs only one copy of the defective gene to develop the disorder. Koshal has Huntington's disease, but his mother does not have Huntington's disease. Koshal and his wife are now expecting a child. What is the probability that their child will have Huntington's disease? 1/4 1/3 1/2
Huntington's disease is an inherited autosomal dominant disorder that can affect both men and women. Imagine a couple has had seven children, and later in life, the husband develops Huntington's disease. He is tested and it is discovered he is heterozygous for the disease allele, Hh. The wife is also genetically tested for the Huntington's disease allele, and her test results show she is unaffected, hh. What is the probability that any four of the seven children will have Huntington's disease? probability:
