The presence of a cell line with the Y chromosome SRY locus in females or the presence of a 45,X cell line in males has the greatest influence on gender appearance and sexual development. The females are XX and produce egg cells that contain an X chromosome. Both males and females develop when eggs are incubated at temperatures ranging between those that induce only single-sex development.

The indirect sex differences come from hormones. Because males have only one X chromosome, the altered trait would always be expressed in males. The great majority of nonmosaic 45,X conceptions do not survive to term. Article Media.

  • Chromosomes are long segments of genes that carry hereditary information.
  • Sex chromosome , either of a pair of chromosomes that determine whether an individual is male or female. The sex chromosomes of human beings and other mammals are designated by scientists as X and Y.

  • Aug 11,  · Adult males lack the Y sex chromosome that humans have and have only an X chromosome. They produce sperm cells that contain either an X chromosome or no sex chromosome, which is designated as O. The females are XX and produce egg cells that contain an X chromosome. If an X sperm cell fertilizes an egg, the resulting zygote will be XX, or female. The X and Y chromosomes are the two sex chromosomes in humans. Females have two X chromosomes, whereas males have one X and one Y chromosome. It is believed that the X was named by earlier researchers as unknown and the Y was named alphabetically after X. Compared with the 22 pairs of autosomes in humans, the pair of the sex chromosomes is unique in many aspects.

  • A sex chromosome is a type of chromosome that participates in sex determination. Humans and most other mammals have two sex chromosomes, the X and the Y. Females have two X chromosomes in their cells, while males have both X and a Y chromosomes in their cells. Egg cells all contain an X chromosome, while sperm cells contain an X or Y chromosome. The eggs fertilized by X-bearing sperm become females (XX), whereas those fertilized by Y-bearing sperm become males (XY). Unlike the paired autosomes, in which each member normally carries alleles (forms) of the same genes, the paired sex chromosomes do not carry an identical complement of genetic information.

  • Apr 28,  · In the XY system, males contain one X and one Y chromosome, while females contain two X chromosomes. Thus, males are considered heterogametic – they can produce two different types of gametes, depending on whether the sperm carries an X or a Y chromosome. Females are homogametic – all their eggs carry one X chromosome. Female (XX) mammals inherit one X chromosome from each parent, but males (XY) receive an X from their mother and a Y sex chromosome from their father. .

  • Apr 04,  · Male vs Female Chromosomes. Male and female chromosomes are the sex determining chromosomes of an organism. These are also known as gonosomes. Numerous models are used for sex determination in organisms. XY system is used by humans, most mammals, some insects, and some plants. Other mechanisms available are XO system and ZW system. There are various phenotypes due to the effects of human sex chromosome variations like Turner's and Klinefelter's syndromes. Turner's (XO) affects females, while Klinefelter's (XXY) affects males. A SRY (sex determining region) on the Y chromosome is male specific (MSY).
