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 cystic fibrosis. The brother of his current wife, Elaine, died of cystic fibrosis. What is the probability that Charles and Elaine will have a baby with cystic fibrosis? (Neither Charles nor Elaine has cystic fibrosis.)

Answers

Answer 1

Answer:

The probability of the couple having a child with cystic fibrosis is 1/4

Explanation:

There is a huge chance both Charles and his current wife have heterogenous genes for cystic fibrosis. This is because Charles and his first wife must have contributed an allele each for the child to have cystic fibrosis. Also, for one of the current wife's siblings to have cystic fibrosis, it shows there parents both had a alleles for cystic fibrosis which could have been passed to her also. Thus, assuming the heterogenous gene for cystic fibrosis is Aa, the probability of them having a baby with cystic fibrosis will be determined by the crossing below.

Aa     ×      Aa

AA  Aa   Aa  aa

Where "A" is the normal allele and "a" is the allele for cystic fibrosis, the probability of the couple having a child with cystic fibrosis is 1/4.

Why might tobacco advertisements target teens?

Answers

Answer:

it might target they by how good c it makes them feel

Answer:

Tobacco advertisments target teens because they know teens dont know the dangers tobacco does to them. For instance, if you tell a child if they want some of THAT, a child will not take it because they are taught to not talk to strangers. A teen might not even care about learning the dangers of tobacco. But it is also very addictive. THats why they make them into different flavors and make them LOOk like school supplies. That way if they already are addicted to the drug, they can sneek it into school so they don't go crazy. Not having the drug can make an addict feel anxious and if they dont get it they could get violent.
