- 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?A couple decided they want to have a total of 7 children. However, they want to set realistic expectations and are trying to figure out how likely they are to get certain combinations. (Assuming the probability of having a boy is equal to the probability of having a girl) what is the probability that a family with 7 children will consist of: Alternating sexesA pregnant woman is carrying a triplet inside her womb. They want to determine the number of boys or girls she is carrying but the sex of the fetus cannot be determined yet. What is the probability of having a boy and at least a girl? O 3a?b O a°
- A man and woman have 5 children, all healthy boys. They would like a daughter. What is the likelihood or probability that their 6th child is a girl? Group of answer choices - Nearly 100% probability that the next child is a girl since have all boys - Less than 50% probability since they seem more likely to have boys - 0% probability. This will be a family of all boys - 50% probability of a girl. The previous births have no bearing on this event - More than a 50% probability that the child is a girl since have so many boysMatch the following letter representations with their genetic term.
