sex drive

sex

1. the fundamental distinction, found in most species of animals and plants, based on the type of gametes produced by the individual or the category to which the individual fits on the basis of that criterion. Ova, or macrogametes, are produced by the female, and spermatozoa, or microgametes, are produced by the male. The union of these distinctive germ cells results in the production of a new individual in sexual reproduction.

2. to determine the sex of an animal.

sex cell

see germ cell, gamete.

sex chromatin

the persistent mass of chromatin situated at the periphery of the nucleus in cells of normal females; it is the material of the inactivated sex chromosome. Called also Barr body.

chromosomal sex

sex as determined by the presence of the XX (female) or the XY (male) genotype in somatic cells, without regard to phenotypic manifestations. Called also genetic sex.

sex chromosomes

see sex chromosomes.

sex determination

1. the change in the fetus to a male or female configuration; the process by which the sex of an organism is fixed, associated, in animals, with the presence or absence of the Y chromosome.

2. diagnosis of the sex of the fetus before birth performed by examination of fetal fluids obtained by amniocentesis.

sex determining region of Y

These hormones influence the secondary sex characters, such as the shape and contour of the body and head, mammary development and the pitch of the voice. The male hormones stimulate production of spermatozoa, and the female hormones control ovulation, pregnancy and the estral cycle.

the sex as determined on the basis of the presence or absence of sex chromatin in somatic cells, its presence normally indicating the XX (female) genotype, and its absence the XY (male) genotype.

sex parity

see sex ratio (below).

sex pheromone

see pheromone.

sex ratio

proportion of female to male births.

sex reversal

the sexual condition of animals in which gonadal sex and chromosomal sex are dissimilar.
