With the consent of her husband, she decided to take fertility pills with the hope that with that medical procedure she would bear a baby. After taking the pills for 14 months, she conceived and was on the start of the 2nd trimester. In her usual check-up with her OB-Gyne, and after an ultrasound procedure, her hope to have a baby had risen to unprecedented proportions. She was told that she was carrying seven (7) babies in her womb. According to her OB-Gyne, she would not be able to have all the babies delivered as the seven would stress too much her uterus and this could be fatal to her and all her babies. Therefore, three of the designated weak babies would have to be removed before the end of the 2nd trimester. Vicky T., got confused and was in limbo. She wanted to be guided whether the procedure was ethical or not. If so, any guilt feelings she felt would be…arrow_forward

What is the probability that Sam, the man’s second oldest son (II-2), will suffer from the disease if he lives a normal life span? Sam’s mother and her ancestors do not have the disease. Sam's father was adopted, so we do not know his biological family history for Huntington disease. Explore all possible outcomes for Sam and explain your reasoning. What about the risk to Sam's sisters? Would that be the same or not?arrow_forward
