These genes are linked to neural crest and central nervous system development. These genes affect embryogenesis and can confer tameness, smaller jaws, floppy ears, and diminished craniofacial development, which distinguish domesticated dogs from wolves and are considered to reflect domestication syndrome. The study concluded that during early ...
The transformation of a phenotypically female child into a phenotypically male adult at puberty, which is reported to be celebrated in Dominican culture, is the result of a genotypic male (with XY chromosomes) born with a deficiency in the enzyme 5α-reductase. 5α-Reductase is responsible for the reduction of testosterone to dihydrotestosterone.
Neoteny is seen in domesticated animals such as dogs and mice. [25] This is because there are more resources available, less competition for those resources, and with the lowered competition the animals expend less energy obtaining those resources. This allows them to mature and reproduce more quickly than their wild counterparts. [25]

A juvenile is an individual organism (especially an animal) that has not yet reached its adult form, sexual maturity or size. Juveniles can look very different from the adult form, particularly in colour, and may not fill the same niche as the adult form. [1] In many organisms the juvenile has a different name from the adult (see List of animal ...
Examples of secondary sex characteristics in non-human animals include manes of male lions [4] and long feathers of male peafowl, the tusks of male narwhals, enlarged proboscises in male elephant seals and proboscis monkeys, the bright facial and rump coloration of male mandrills, horns in many goats and antelopes, [10] and the swollen upper ...

The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child. There are over 6,000 known genetic disorders in humans.
