Using a positional cloning strategy, Matsuda et al. Comparison of the medaka with alternative models, such as the platyfish Xiphophorus maculatus and the tilapia Oreochromis niloticuswill probably contribute considerably to our understanding of the molecular and evolutionary mechanisms driving the variability of sex determination in fish.

  • Melandrium album shows sex chromosomal sex determination. They have X and Y sex chromosomal constitution similar to Drosophila and Human. However, the mechanism of sex determination is quite different from the usual XX – XY system. In Melandrium album, the AAXX individuals will be females and AAXY individuals will be males. Mar 12,  · Chromosomal mechanism of sex determination in animal. reptiles, some fishes and butterflies, moths and in some plant species Frageria orientali., female are heterogametic (ZW) X and Y sex chromosome of Melandrium is similar to that of human or Drosophila but mechanism of sex determination is different from usual XX-XY system.

  • The ZW sex-determination system is found in birds, some reptiles, and some insects and other organisms. The ZW sex-determination system is reversed compared to the XY system: females have two different kinds of chromosomes (ZW), and males have two of the same kind of chromosomes (ZZ). In the chicken, this was found to be dependent on the expression of DMRT1. Genetic determination of sex in fish can involve monogenic or polygenic systems, with factors located on the autosomes or on sex chromosomes. In the latter case, both male (XY) and female (ZW) heterogametic systems have been described, as well as many subtle variations on these themes. Sex chromosomes are found in approximately 10% of fish Cited by:
