Zw Sex Determination
The Y chromosome, that little chain of genes that determines the sex of humans, is not as tough as you might think. In fact, if we look at the Y chromosome over the course of our evolution we’ve seen it…
Alex Quinn, a Ph.D. candidate at the Institute for Applied Ecology at the University of Canberra in Australia, sorts this quandary out for us. Sex-determining mechanisms in reptiles are broadly divided into two main categories: genotypic sex determination (GSD) and temperature-dependent sex

Als eine weitere Folge der chromosomalen Geschlechtsbestimmung liegt in einem der Geschlechter ein Chromosom zweimal vor, das beim anderen nur einmal da ist.

IN his autobiography, Long Walk to Freedom, published in 1994, Nelson Mandela proclaimed: “To be free is not merely to cast off one’s chains, but to live in a way that respects and enhances the freedom of others.” Residents of Harare’s Avenues area would be the best to understand the
Birds and many insects have a similar system of sex determination (ZW sex-determination system), in which it is the females that are heterogametic (ZW), while males are homogametic (ZZ).
