In drosophila gene A and B are $10$ map unit apart on chromosome. A female Drosophila with genotype $\frac{AB}{ab}$ and male Drosophila with genotype $\frac{AB}{ab}$ were crossed. How many type of gametes are produced by female and male Drosophila respectively:

Q. A scientist conducted a crossing experiment with Drosophila. From the experimental results he concluded that crossing over occurs in females but not in males. From this information, choose the correct statement regarding the types of gametes produced by the female and the male flies. The male and female both have the same genotype (AB/ab).

Q. Bridges crossed this female with a normal male and observed many Karyotypes in the offspring in Drosophila. Identify the female genotype.

Q. Drosophila flies with XXY genotype are females, but human beings with such genotype are abnormal males. It shows that:

Q. How many types of gametes will be produced by female Drosophila having following arrangement of two genes $(y^{+},w^{+})$ on X-chromosomes?
