In nondisjunction, if members of a pair of homologous chromosomes do not move apart during meiosis I or sister chromatids fail to separate during meiosis II, this means one gamete receives 2 of the same kind of chromosome and i<span>f either one of these abnormal gametes unites with a normal one at fertilization, the zygote will also have an abnormal number of particular chromosomes; which is known as an aneuploidy.</span>
Traits such as skin color and height are variable throughout the human population because these traits are controlled by more than one cell. The cells don't perform at the same rate and don't produce the same biomolecules. Therefore, the maximum height of a person is not achieved which results to variations.

Gluconeogenesis is a
metabolic pathway that results in the generation of glucose from non-carbohydrate
molecules, from breakdown of amino acids or fatty acids and from other steps in
metabolism that include pyruvate and lactate. This pathway is one of several
main mechanisms used by humans and many other animals to maintain blood glucose levels<span>, avoiding low
levels of blood glucose.</span>
