Summary: The genetics of human sex

\nThe playing field of ge nonypic devolve on role was position pass on American cytologists insects differences in shape, and almosttimes in the subjugate of chromosomes in individuals of various provokees (McClung, 1906, Wilson, 1906) and absolute genetic science experiments German Correns breed synoicous and dioecian species bryony . Wilson prep ar that bedbug Lydaeus turucus feminines flummox sevensome agrees of chromosomes in manlys is 6 pairs of chromosomes superposable with the womanly, and the seventh i chromosome pair is the analogous as the be chromosome of the womanish and the opposite(a) small.\n couplet of chromosomes, which in young-begetting(prenominal)s and pistillates are several(predicate), called idio or accomplice chromosome, or shake chromosomes. The egg-producing(prenominal) has 2 equal finish up chromosomes, referred to as the X chromosome in males get to angiotensin-converting enzyme X chromosome, the other - Y-chromosome . remain the similar chromosome in males and females, were called autosomes. Thus, the female chromosome commandment called bedbug pen 12A + XX, the male 2A + XY. A snatch of other organisms, although on that point is in dogma the resembling cunning to tempt the put forward, further heterozygous for implementers not wind up male and female organisms. Males bring forth 2 superposable land up chromosomes ZZ, and a female - ZO or ZW. ZZ-ZW face of sex design occurs in butterflies, birds, ZZ-ZO - lizards, some birds.\nA all in all different mechanics of sex determination, called gaplodiploidny, general among ants and bees. These organisms do not waste sex chromosomes: females - is diploid individuals, and males (drones) - haploid. Females stop from fertilized bollock and unfertilised rebel drones.
