During the fourth century BC, many philosophers believed that the baby's sex was determined by the origin of the production of the seminal fluid of the father. If it was produced by the right testicle, would be a boy if, at left, a girl. Later, it was thought that sex was defined after fertilization, taking into account environmental factors. There are reports that in the sixteenth century, the King of England, Henry VIII, abandoned several wives because they were not able to give him an heir. Of the six marriages, only the third wife, Jane Seymour, gave her a son, then Prince Edward VI, who died at age 16. The king ignored their own sperm is that defined the sex of the future baby. It was only with the recognition of male and female gametes, more precisely with the knowledge of the chromosomes in the nineteenth century, those answers on sex determination. Men and women, what makes us so different? The so fabulous human machine consists of 46 chromosomes arranged in 23 pairs of these, 44 chromosomes, or 22 pa- res, are called autosomes and are responsible for formation of the body as a whole. Two chromosomes, or a pair are called sex chromosomes and are responsible for sex determination. These forms have different sex chromosomes in man, being a lot bigger than the other (non-homologous sex chromosomes). In women the two chromosomes are keyed alike (homologous sex chromosomes).

Homologous chromosomes: chromosomes are in pairs in diploid cells, have the same number and sequence of genes for certain inherited traits. Heterologous chromosomes: chromosomes are in pairs in diploid cells DO NOT have the same number and sequence of genes for certain inherited characteristics, could be considered partially counterparts.

U četvrtom stoljeću prije Krista, mnogi filozofi vjerovali da spol djeteta je određen podrijetlu proizvodnju sjemene tekućine od oca. Ako je proizveden po desnoj testisu, bi li dječak, na lijevoj strani, djevojka. Kasnije, on je mislio da je seks bio definiran nakon oplodnje, uzimajući u obzir ekološke čimbenike. Postoje izvješća da je u šesnaestom stoljeću, kralj Engleske, Henrik VIII, napuštena nekoliko žena, jer oni nisu bili u mogućnosti dati mu nasljednika. Od šest brakova, tek treća žena, Jane Seymour, dao joj je sin, zatim Prince Edward VI, koji je umro u dobi od 16 godina. Kralj ignorirati vlastitu spermu koja se definira spol budućeg djeteta. To je samo uz priznavanje muških i ženskih spolnih stanica, točnije sa znanjem kromosoma u devetnaestom stoljeću, te odgovore na određivanje spola. Muškarci i žene, ono što nas čini toliko različiti? Tako nevjerojatan ljudski stroj se sastoji od 46 kromosoma raspoređenih u 23 parova od tih, 44 kromosoma, odnosno 22 Pa- res, nazivaju autosomni kromosomi te su odgovorni za formiranje tijela kao cjeline. Dva kromosomi, ili par se zove spolni kromosomi i odgovorni su za određivanje spola. Ovi oblici imaju različite spolnih kromosoma u čovjeka, što je puno veća od ostalih (non-homologne spolnih kromosoma). U žena su dva kromosoma su učvršćeni podjednako (homologni spolni kromosomi). Napomena: Zastupljenost XX i XY kromosoma. Biologija Sumnje u terminologiji ... Idi na adresu www.cib.org.br / glossario.php i napraviti termin. Homologni kromosomi: kromosomi u paru u diploidnim stanica, imaju isti broj i redoslijed gena za određene nasljedne osobine. Heterologni kromosomi: kromosomi u paru u diploidnim stanice nemaju isti broj i redoslijed gena za nekih nasljednih svojstava, može smatrati djelomično kolegama.
