Huntington’s disease, is an incurable neurodegenerative genetic disorder that affectsmuscle coordination and some cognitive functions, typically becoming noticeable inmiddle age. It results from an autosomal dominant gene (H) and there are no carriers ofthe disease. Two parents with Huntington’s disease have an affected child. What is theprobability that their next child will be an unaffected girl if they are not double-dominant?
In humans, the gene for albinism (a) is recessive to the gene for normal skin pigmentation (A). If two heterozygous persons have children, what is the probability they will have a child who is an albino? What is the probability they will have a child that is a carrier of the recessive gene?
Retinitis pigmentosa, a form of blindness in man, maybe caused either by a dominant autosomal gene R, or a recessive autosomal gene a. An afflicted man whose parents are both normal marries a woman with genotype AaRr. a. What proportion of the children are expected to suffer from this affliction if R and A are inherited independently? b. If this couple want to have normal children only, what isthe probability of having normal children?
Circle any inheritance patterns that could explain this pedigree. Assume individuals marrying into the family do not have a mutant allele. Please refer to the image attached. A) Paternally imprinted B) Maternally imprinted C) Maternal inheritance D) Autosomal recessive E) Autosomal dominant F) X-linked recessive G) X-linked dominant
In 1995, doctors reported a Chinese family in whichretinitis pigmentosa (progressive degeneration of theretina leading to blindness) affected only males. Allsix sons of affected males were affected, but all of thefive daughters of affected males (and all of thechildren of these daughters) were unaffected.a. What is the likelihood that this form of retinitispigmentosa is due to an autosomal mutationshowing complete dominance?b. What other possibilities could explain the inheritance of retinitis pigmentosa in this family? Whichof these possibilities do you think is most likely?
