Meiosis, or reductional division, is a process during which exchange of genetic material between the homolog chromosomes (crossing-over and recombination) takes place and such a division of the genetical material occurs the four daughtercells
have received each only one set of chromosomes (they are haploid, in
contrast to the mother cell which contained homolog chromosomes and was
diploid)
<span>have each a distinct genetical composition, also different from that of the parental cell.
Meiosis is divided into twofases: meiosis I and meiosis II.

Answer:
X is negative heterotropic modulator
Explanation:
In allosteric regulations, modulators are molecules that causes a change in the conformation of an enzyme, hence, resulting a change in enzyme activity. It can lead to a decrease or an increase of the enzyme. When a molecule decreases the enzyme activity it called a negative modulator, when it increases or activates the enzyme activity, it is called a positive modulator.
A positive or negative modulator can either be homotrophic (substrate acts as modulator) or heterotropic (another ligand acts as modulator).
In the example above, X is negative heterotropic modulator, because the modulator is different from the substrate and it also decreases the enzyme activity.
