- A couple who wishes to have children visits you, a genetic counselor. There is a history of a deleterious recessive trait in males in the womans family but not in the mans family. The couple is convinced that because his family shows no history of this genetic disease, they are not at risk of having affected children. What steps would you take to assess this situation and educate the couple?Unattached earlobes (E) are dominant over attached earlobes (e) [Figure (a) and (b)]. If a woman with unattached earlobes and a man with attached earlobes have children, what percentage of their children has the possibility of having unattached earlobes if the mother is homozygous for the trait?There is a couple, the blood type of a male is A+ and the female is o+. What are all the possible blood types of their children in the future? Illustrate the inheritance in a Punnett Square showing all the possible blood types from the offspring of the male and female.
- What is the probability that a parent carryinga dominant trait will pass that trait on toeach child?Cystic fibrosis is a recessive genetic disorder. Ron is homozygous dominant (FF) and Nancy is a carrier (Ff) of cystic fibrosis. Use a Punnett square to predict the probability that one of their children will have cystic fibrosis?A child is born to a mother whose blood group is IA1 and a father whose blood group is O. The child is of blood group IA2. Which of the following is true? Group of answer choices: This is a normal case in inheritance. The child’s genotype is IA2 IA2 The mother has Bombay blood group The child’s father is some other man
- Attached are three pedigrees. For each trait, considerwhether it is or is not consistent with X-linked recessiveinheritance. In a sentence or two, indicate why or why not.A woman who is heterozygous, Bb, has brown eyes; B (brown) isthe dominant allele, and b (blue) is recessive. One of her eyes,however, has a patch of blue color. Give three different explanationsfor how this might have occurred?Huntington disease is a rare fatal, degenerative neurological disease in which individuals start to showsymptoms in their 40s. It is caused by a dominant allele. Joe, a man in his 20s, just learned that his fatherhas Huntington disease.a. What is the probability that Joe will also developthe disease?b. Joe and his new wife have been eager to start afamily. What is the probability that their first childwill eventually develop the disease?
- Assume for a moment that a child has a autosomal recessive disorder, but both parents appear normal. What is the genotype of both parents? : one parent must be homozygous dominant : both parents must be homozygous recessive : both parents are heterozygous : both parents nust be homozygous dominantJohn has unattached earlobes (dominant) like his father, but his mother has attached earlobes (recessive). What is John’s genotype? Show punnet squareIf the statement is made by a friend that both of my parents have trait X, and I do not so I must be adopted. Consider the limitations on the classic laws of Mendelian Inheritance and write your response to your friend regarding that friend's potential parentage. Does looking different mean that there is no possible genetic relationship between student and parents? In 4 sentences provide your response. answer must be unique dont copy from anywhere else
