If you add more things to one element from the periodic table it will no longer be what it's original state was. For example, (this is not accurate) iron, the atomic number is 10, if you add like 23, you will get a completely different element. Say silver is 56, you add copper (20), it will no longer be silver.

erastova [34]

Complete question:

Imagine that a newly discovered, recessively inherited disease is expressed only in individuals with type O blood, although the disease and blood group are independently inherited.

A normal man with type A blood and a normal woman with type B blood have already had one child with the disease. The woman is now pregnant for a second time.

Assuming that both parents are heterozygous for the gene that causes the disease, what is the probability that the second child will also have the disease? Express your answer as a fraction using the slash symbol and no spaces (for example, 1/2).

Answer:

The probability that the second child will also have the disease is 1/16.

Explanation:

Available data:

Two genes independently inherited: one for blood type, the other for disease
Man with type A blood x Woman with type B blood
Both parents are heterozygous for the gene that causes the disease; Dd

If the man has A blood, and the woman has B blood, and they already have an affected child, this means that they must be heterozygous for blood type too.
