Imagine that you are a genetic counselor, and a couple planning to start a family comes to you for information. charles was married once before, and he and his first wife had a child with:

1/6 or 16.7%

Explanation:

In order for the child to be born with cystic fibrosis there needs to be two recessive alleles for the disease to develop. Based on the situation it seems that Charles is a carrier, but since Elaine's parents had one kid with and one kid without cystic fibrosis then they are carriers, meaning that Elaine can either have two healthy alleles or be a carrier as well. Therefore the probability that Charles and Elaine will give to the child the recessive allele together is that of 1/6 (1/2 from Charles x 1/3 from Elaine), making that approximately 16.7%.

for me i have felt invisible when i was clearly struggling,or,i made a great achievement ,and,nobody took to notice me either because they just didn't see it,or,people just turned their back on me.i can see a person being invisible by choice,or,without choice like i did.the people who are invisible by choice don't try to talk to people,don't try to make friends,and,keep to themselves.i haven't been one of those people so i couldn't give you a reason.
