The hormone vasopressin stimulates the kidneys to retain water.
Vasopressin or antidiuretic hormone is secreted by the posterior pituitary gland and acts on the nephron tubules which increase the reabsorption of water, thus decreasing water content in urine while increasing that of blood.
The increase in water concentration in the blood elevates blood pressure as well as blood volume which makes the urine concentrated.
It regulates the tonicity of body fluids and therefore, in response to hypertonicity stimulates the kidneys to reabsorb solute-free water and return it to the circulation from the tubules of the nephron, thus restoring the tonicity of the body fluids toward normal.

Meiosis involves crossing over where chromosomes exchange genetic segments, resulting in different sets of chromosomes. Each time an egg or sperm created, it is different due to this recombination. Mitosis on the other hand is non-sex cells replicating exact copies of themselves which lead to no genetic variation as they aren't involved in producing offspring.
