William and Quentin are fraternal twins. This means they share, on average, what % of genes with one another?
nordsb [41]

Answer:

The correct answer is 50%

Explanation:

Fraternal twins are the twins which are produced from the fertilization of two different eggs by two different sperms. These eggs are released at the same time.

So as fraternal twins are produced from fertilization of two different eggs therefore they share 50% of genes with each other just like other siblings. They are also called dizygotic twins

Identical twins are produce from a sigle fertilized cell which later divides into two cell mass. Indentical twins share 100% gene. Therefore the correct answer is 50%.

What is a reducing sugar?
icang [17]
Reducing sugar is any sugar (all monosaccharides, some disaccharides, oligosaccharides, and polysaccharides) that is capable of acting as a reducing agent because it contains free aldehyde group or free ketone group.

Aldehyde group or alkanal is an organic compound containing formyl group. The formyl group is a functional group consisting of a carbonyl center bonded to hydrogen and an R group. This group can be readily reduced to primary alcohol with the help of catalyctic hydrogenation either applied directly or by transfer hydrogenation.

Ketone group unlike aldehyde group does not have a hydrogen atome bonded to the carbonyl group but it can still be hydrogenated.
