Jermaine and Shikia are healthy parents of three young children. The oldest two, Bethany and Amber, are healthy, and they are six and four, respectively. Their youngest child, Roscoe, was born with Peeling Skin Syndrome two years ago. Roscoe's skin constantly peels, and is red and itchy. If Jermaine and Shikia have another child, the probability that he or she will inherit the skin condition is .a. 1/4.
b. 1/8.
c. 2/3.
d. 1/3.

The correct answer is A.

Explanation:

They have three children and the peeling skin syndrome is present in one of them but this does not affect the probability of their fourth children having this disease.

Peeling skin syndrome is a disorder that is autosomal recessive which means that it is triggered when the child has two recessive genes that is responsible for the disorder from both of his/her parents.

Considering the parents are healthy but they both possess the recessive genes for the disorder, they are heterozygous.

In that case the probability that their fourth child inheriting the disorder is 1/4.

I hope this answer helps.

A. 1/4.

Explanation:

Peeling skin syndrome is an autosomal recessive disorder in which individual's skin constantly peels, red and itchy.

In above scenario Jermaine and Shikia's two children are healthy and one younger children has Peeling Skin Syndrome which is autosomal recessive disorder.

So, it means both parents are heterozygous for this syndrome.

Then the probability for next child to inherit the skin condition is 25% or 1/4 according to punnett square.

answer; the above statement is (true);
