. Jack and Jill are thinking about starting a family and they come to you with a question about a rare recessive genetic disease

called Alpers Syndrome. Alpers causes progressive neurodegeneration in infants and children and is usually lethal within the first 10 years of life. Jack's grandfather had a brother die of Alpers Syndrome, while Jill has no family history of the disease. If the frequency of heterozygotes for Alpers is 1 in 2000 in the general population, what is the chance that Jack and Jill will have a child with Alpers Syndrome? (Be sure to completely reduce your answer.)

Answer:

The chance of  having a Child who is a Heterozygote  is 50% , The chance of having a child that will completely come down with Alpers syndrome is 0%

Explanation:

Jack  has a history of Alpers in his family

Jill has no history

lets assume Jack is a carrier : Ab ( because that is how he could have survived the first 10 lethal  years )

Jill : AA

Therefore the probability/chance of Jack and Jill having a child with Alpers ( carrier ) syndrome will be 50 % as shown below

AA * Ab = AA , Ab, AA, Ab

The child produced by Jack and Jill will only be a carrier of the syndrome and not completely affected by the syndrome

What are the cause and effect relationships driven by variations in the flow of energy into and out of Earth's systems?
ValentinkaMS [17]

A balance of this two process must be maintained in order to attain a constant earth temperature.

<h3>Energy flow in the earth</h3>

The earth in itself is a massive ecosystem. Energy flows into the earth and out of it. The only source of energy input to the earth is the sun. Also, energy is lost from the earth via re-radiation of energy in the form of infrared rays.

However, this inflow and out flow of energy affects the temperature of the earth. A balance of this two process must be maintained in order to attain a constant earth temperature.

Why Do Reptiles Have a Third Eye
nikdorinn [45]
The third eye is called the parietal eye. Although it has a lens, retina and nerve connection, it is not functional as an eye. it grows on top of the reptile's head, under the skin, and is not visible.

<span>Scientists have not been able to determine the function of this third eye, but it is thought that light falling on this third eye may influence certain biological functions such as sleep and hibernation.

Hope this helps!
