Parental (genetics)

In biology and particularly in genetics, the parent or progenitors of a progeny, that is, the individual or individuals whose reproduction, whether sexual or asexual, causes the transmission of a genetic inheritance is called parental. > In biology we also call intraspecific relationships to the biotic relationships that are established between organisms of the same species and this divides into a family degree or degree of kinship in:

Family associations can also be:

In the case of humans, the parents are the father and the mother. In the case of living beings that reproduce asexually, for example by binary fission, the stem cell, after its division, originates two daughter cells, that is, it doubles, but there is no death for it.

In the case of species that have anisogenic gametes, which is almost always related to the presence of an egg, the fruit of the mother and large, and a spermatozoon, from the father and small, the greatest nutritional contribution to the future stem is provided by the mother. In addition, in terms of DNA content, the mother provides more genetic information, since there is genetic material outside the nucleus (which is transmitted equitably by the two parents), in particular that of mitochondria and, in plants, of plasters, which are transmitted exclusively through maternal inheritance.
