In many plants and animals with distinct sexes, the genes responsible for sex determination may be located on a special chromosome pair: sex chromosomes (or allosomes). All other chromosomes are known as autosomes. A human carries 46 chromosomes; 22...

The sex of an individual is usually determined by the sex chromosomes that the organism has. Each diploid cell in the organism has one pair of sex chromosomes that differs from the other homologous pairs of chromosomes. For example, in humans, one of...

Sex chromosomes are the chromosomes within a cell that determine the sex of an organism. In all organism cells, with the exception of the sperm and eggs and the gametophyte generation in plants, chromosomes are arranged in pairs called homologous...

The sex of an individual is determined by the genetic information present in the individual's sex chromosomes. Each diploid cell has one pair of sex chromosomes that differs from the other homologous pairs of chromosomes. For example, in humans, one of...

A sex-determination system is a biological system that determines the development of sexual characteristics in an organism. Most sexual organisms have two sexes. In many cases, sex determination is genetic: males and females have different alleles or...

INTRODUCTION Sex determination is a process that leads to the physical separation of male and female gamete-producing structures to different individuals of a species. Even though sexually reproducing species have only three possible options-to relegate the two sexes to separate individuals, to keep...

Employee promotions at the federal agency that regulates credit unions were based on workers' race and sex, not merit, according to internal agency directives. Karl T. Hoyle, executive director of the National Credit Union Administration until he was removed from his post...
