The specific temperatures required to produce each sex are known as the female-promoting temperature and the male-promoting temperature. Hence, sex determination is genetically programmed during fertilization, but sex differentiation, the second phase of sexual development, is hormone-dependent [ 5 ].

In this variant of the XY system, females have two copies of the sex chromosome XX but males have only one X0. There are two basic phases of sexual development in mammals: sex determination at fertilization and sex differentiation that is associated with sex determination but may be influenced by a variety of internal factors mainly hormones and their receptors and external factors hormones, endocrine disruptors, and a variety of environmental chemicals [ 2 ].

This is because the male who inherits the recessive allele on his X chromosome has no allele on his Y chromosome to counteract its effects. The sex chromosomes carry genes that determine whether a person is male or female. Note that this assumes that all ancestors of a given descendant are independent, but if any genealogy is traced far enough back in time, ancestors begin to appear on multiple lines of the genealogy, until eventually, a population founder appears on all lines of the genealogy.

Transcaucasian mole voles Ellobius lutescens also have a form of XO determination, in which both sexes lack a second sex chromosome.
