A young couple went to see a genetic counselor because each had a sibling affected with cystic fibrosis. (Cystic fibrosis is a r
mel-nik [20]

Answer:

a) The correct answer is 1/2 or 0.5

Cystic fibrosis is a recessive disorder and her sibling has a disease but none of the parents had it. Thus, each of the parents must be the carrier of the disease, that is, both of them must be heterzygous.

So, if we cross Cc x Cc, it results in the genotype ratio of 1 (CC) : 2 (Cc) : 1 (cc)

Thus, 2 out of 4 would be the carrier of the disease.

b) 1/16

The probability of female to the carrier is 1/2

Same is the case with male partner due to the probability that he would be the carrier is 1/2

If both are carrier then, there is only 1/4 chances that the offspring will have the disease (as per cross shown above).

Now, the probability that the offspring will have the disease = product of all the above probabilities. (The probability of occurrence of two independent events is equal to the product of their individual probabilities).

So, \frac{1}{2}x\frac{1}{2}x\frac{1}{4} = \frac{1}{16}

c) 1/8

The probability of female to be the carrier is 1/2

The probability male to be the carrier is 1/2

If both are carrier then, there is only 2/4 chances that the offspring will be the carrier of the disease (as per cross shown above).

Now, the probability that the offspring will be the carrier = product of all the above probabilities. (The probability of occurrence of two independent events is equal to the product of their individual probabilities).

\frac{1}{2}x\frac{1}{2}x\frac{2}{4} = \frac{1}{8}

konstantin123 [22]

Answer:

Antigens

Explanation:

Antigens can be defined as molecules that can bind to antibodies. Many authors prefer to define it as any substance capable of eliciting a response from the immune system, however there are antigenic substances that react with the antibody but are not able to stimulate its production.

Antigens are usually unknown molecules in the body. Molecules that detach from foreign cells such as bacteria, fungi, protozoa or even viruses can be considered antigens. Toxins released by bacteria are also examples of substances that can bind to antibodies.

When an individual's blood-type alleles have instructions that direct the construction of a specific set of chemicals that protrude from all red blood cells, these chemicals are the antigens.
