Unbelievable, but the portion of the non-homologous chromosome X and Y because a lot of things ... Genes that are found exclusively located on the X chromosome, in its non-homologous portion, determine the sex-linked inheritance. As this legacy is evident, he was the first "model" of inheritance recognized in humans, initially presenting the largest number of features. When a gene is sex-linked recessive lethal, mortality is lower in women, occurring only in homozygous. Death in men is higher, since it occurs only in the presence of a lethal gene, due to the presence of a single X chromosome Likewise, if the gene "defective" portion is located in the non-homologous X chromosome abnormality reach a higher incidence males. The females will only display the "disease" homozygous. In heterozygous carriers will only. There are instances in which the gene "defective" is located in the non-homologous portion of chromosome Y. These genes are called holândricos and restricted to males, since only men carry the Y chromosome in their karyotype. In this case, we talk about heritage restricted to sex. Read the example in Figure 1: FIGURE 1 - Represents hypertrichosis, a disease that borders on fiction, struck Pedro Gonzales. Born in Tenerife, Canary Islands, in 1556, Peter was given as a present to the court of Henry II, like a stuffed animal. He had three children (two girls and a boy) and a grandson, all male descendants with the same disease. One of the first known cases of congenital universal hypertrichosis was therefore of Pedro Gonzales. Because of his intelligence and his commanding presence, Henry II made him one of their most important ambassadors. His children came to be shown in court during parties promoted as examples of "how nature evil could invade a human body sinner." Source: ZAPPIS OF LAVINIA FONTANA (1552-1614), Gonzáles, 1585, belongs to Castle Ambras, Innsbruck, Austria. Technique: Oil on canvas. We still have the legacy of sexual characteristics determined by genes not located on the sex chromosomes. In this situation, the character has its manifestation in one sex and the other does not. This event happens because of anatomical or hormonal differences between males and females. Denominated is then limited inheritance sex.

Nevjerojatno, ali dio non-homologne kromosoma X i Y, jer puno stvari ... Geni koji se nalaze isključivo nalazi na X kromosomu, u svom non-homolognog dijela, utvrditi sex-linked nasljedstvo. Kao što je to nasljeđe je vidljivo, on je bio prvi "model" nasljeđivanja priznat u ljude, u početku predstavljanja najveći broj mogućnosti. Kad je gen sex-linked recesivan smrtonosna, smrtnost je niža u žena, javljaju samo u homozigotnim. Smrti u muškaraca je veći, jer se pojavljuje samo u prisutnosti smrtonosne gena, zbog prisutnosti jednog X kromosoma Isto tako, ako je taj gen "neispravan" dio koji se nalazi u ne-homolognog X kromosoma abnormalnosti postići višu incidenciju mužjaka. Ženke samo da će prikazati "bolest" homozigotnim. U heterozigotnih prijevoznici će se samo. Postoje slučajevi u kojima je gen "neispravan" nalazi u ne-homolognom dijela kromosoma Y. Ovi geni su pozvani holândricos i ograničen na muškarce, jer samo muškarci nose Y kromosom u kariotipom. U ovom slučaju, govorimo o baštini ograničena na seks. Pročitajte primjer na slici 1: SLIKA 1 - Predstavlja hipertrihoze, bolest koja graniči s fantastikom, udario Pedro Gonzales. Rođen je u Tenerife, Kanarski otoci, 1556, Petar je dobio kao poklon na dvoru Henrika II, kao i plišane životinje. On je imao troje djece (dvije djevojčice i jedan dječak) i unuk, svi muški potomci s istim bolesti. Jedan od prvih poznatih slučajeva prirođene univerzalne hipertrihoze je, dakle, od Pedro Gonzales. Zbog svoje inteligencije i njegov zapovjednik prisutnost, Henry II ga je učinilo jednim od svojih najvažnijih veleposlanika. Njegova djeca, čak će biti prikazan na sudu tijekom stranaka promovira kao primjera "kako se priroda zla mogao upasti ljudskog tijela grešnika." Izvor: ZAPPIS OF Lavinia Fontana (1552-1614), Gonzales, 1585, pripada Dvorac Ambras, Innsbruck, Austria. Tehnika: Ulje na platnu. Mi još uvijek imamo nasljeđe spolnih obilježja određenih gena se ne nalazi na spolnih kromosoma. U ovoj situaciji, lik ima svoju manifestaciju u jednog spola, a drugi ne. Ovaj događaj se događa zbog anatomskih ili hormonalne razlike između muškaraca i žena. Denominiran je ograničeno onda nasljeđivanje spola.
