Discussion Factors and mechanisms of the stopping recombination between X and Y chromosomes are still controversial Polytene chromosomes also reveal an independently derived pericentric inversion in Muller's element C of D. This evolutionary strategy purifies the X chromosome from defective alleles and leads to the larger number of females than males in the population.

Therefore, we ran two additional types of simulations. The male-specific region of the human Y chromosome is a mosaic of discrete sequence classes.
