What is the genotype of the male Drosophila?

Normally, flies have either one or two X chromosomes and two sets of autosomes. If there is but one X chromosome in a diploid cell (1X:2A), the fly is male. If there are two X chromosomes in a diploid cell (2X:2A), the fly is female (Bridges 1921, 1925). Thus, XO Drosophila are sterile males.Click to see full answer. Likewise, people ask, what is the genotype of the male fruit fly?In fruit flies, the Y chromosome is structurally different from the X chromosome, and it doesn’t carry genes that are complementary to those on the X, so any gene that is on the X in a male will be expressed, while the regular rules of dominant and recessive inheritance apply to female flies because they carry two XLikewise, why is Drosophila male fly referred to as Heterogametic? A male fruit fly has XY sex chromosome and Female fowl has ZW sex chromosomes. Since both produce two types of gametes they are called heterogametic. they produce one type of gametes ans so are called homogametic. Furthermore, what is the chromosomal ratio required for a wild type male Drosophila to develop? In Drosophila, the chromosomal basis of sex determination is due to the ratio of X chromosomes to sets of autosomes. A normal 2X Drosophila diploid (XX AA) has an X:A ratio of 1.0 and is phenotypically female. An XY diploid (XY AA) has an X:A ratio of 0.5 and is male; an XO diploid also is male (although sterile).Why Drosophila is used in genetic studies?75 per cent of the genes that cause disease in humans are also found in the fruit fly. Drosophila have a short, simple reproduction cycle. Fruit fly are small (3 mm long) but not so small that they can’t be seen without a microscope. This allows scientists to keep millions of them in the laboratory at a time.
