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.

Which of the following statements about the monomers and polymers found in living organisms is

hodyreva [135]

Answer: Option C is false.

Explanation:

Hydrolysis is the breakdown of compounds(polymers) into simpler substances(monomers) using water. Monomers on the other hand are joined together by a process called dehydration synthesis or polymerization, where the hydroxyl group of one monomer binds to the other, forming a covalent bond.
