Answer:
Its a male, without down syndrome
Explanation:
The fact that it's a male is indicated from the presence of the Y chromosome. In order for this man to have down syndrome, he would have had 3 chromosomes at 21, which he doesnt, meaning he doesnt have down.

Solution : In feedback inhibition, product of a reaction inhibits the enzyme catalysing that reaction. It is a type of control mechanism at the enzyme level. If the product is produced in sufficient amount, in inhibits the enzyme to stop the further production.
Answer:
B) The tall version of the gene is dominant to the short version of the gene.
Explanation:
In the question, its given that both the pea plants are purebred for genetically for height. Therefore, we can already pre-determine the combination of letters for each gene, since purebred means that both letters in the combination are the same.
Tall genes: TT
Short genes: tt
Inputting these into a punnet square would give a result of four possible combinations for the offsprings height:
Tt, Tt, Tt, and Tt (doesn't matter which letter is first)
If <em>all</em> the offspring are tall, despite there being a purebred short parent, then we can assume that the tall gene is dominant to the short gene. (Dominant alleles when paired with sub. alleles have the result of the dominant gene actually showing up. In this case, Tt, where the plant is tall due to the T allele regardless of the presence of the short allele t.)
Hope that helped!
Some chemicals can alter the shape of some enzymes, heat also works (think cooking).
