Hereditary determination of sex
Primary sex determination- Concerns the determination of the gonads. In mammals, determination strictly chromosomal; not influenced by the environment. Most cases- female = XX; male= XY Every individual organism has atleast one X Chromosome. Since the female has 2 X chromosomes, each of her eggs posses one X chromosome. The male posses an X and a Y, so therefore the male can produce 2 kinds of sperm, one with an X chromosome and one with a Y chromosome. If an offspring receives an X and a Y, then it TheY chromosome carries a gene that encodes a testis determining factor. If a person had an innumerable number of x chromosomes and one y chromosome, they would be male. If a person is born with only a single x chromosome and no second x or y, then they develop as a female, but are infertile.(not able to More Primary Sex Determination- In the is absence of the Y chromosome , the primordial gonad body develops into ovaries. the ovary then produces the estrogenic hormones, which contains estrogen and other such hormones, enabling the development of the Mullerian duct into the uterus, fallopian tubes, and upper end of the v
