A prospective groom, who is healthy, has a sister with cystic fibrosis (CF), an autosomal recessive disease. Their parents are n
son4ous [18]

Answer:

Explanation:

From the given information:

Since the parent are normal; Let assume that their trait is Pp

The affected sister  will be recessive in nature, so the trait will be pp

Now, the husband who is the groom will be a carrier with a probability of 2/3 since her sister is affected.

Also, the wife will be carrying a heterozygous trait since she is normal as well.

However, using Hardy-Weinberg assumption:

q^2 = \dfrac{1}{2500}= 0.0004

q = \sqrt{0.0004}

q = 0.02

Recall that:

p+q =1 \\ p = 1 - q \\p = 1 - 0.02 \\p = 0.98\\

Thus, p^2 = (0.98)^2

p^2 = 0.9604

2pq = 2 \times 0.98 \times 0.022

2pq = 0.0392

Finally, the required probability that there will be an affected offspring amongst the family is:

= \dfrac{1}{4} \times \dfrac{2}{3} \times 0.0392

= \dfrac{1}{153}

The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.

<h3>What is the indirect evidence that helped us determine the layers?</h3>

Use of seismic waves is the indirect evidence that helped us determine the layers. When earthquakes occur they produce seismic waves.

The flow of matter occurs by convection. The dense crust subducts back into the mantle exert forces on crustal plates that then move, producing tectonic activity.

So we can conclude that The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.
