Chromosomes X and Y
Conflict
The conflict that Ridley discusses is that each of the X and Y chromosomes are only attracting genes that are beneficial to that sex. This means the X chromosome is more likely to get more feminine genes and genes that are more helpful to the female reproductive system. The Y chromosome, on the other hand, recieves the masculine genes which attracts genes for large muscles and less body fat. The Y chromosome is outnumbered three to one by the X chromosomes. It has to fight extra hard to compete with them. The conflict between the genese from seduction and the genes that is used fro resistance is what keeps the molecular biology of sex in balance. These constant battles between genes and the balance that results is the reason why individuals compete with each other through continually advancing forms of seduction and resistance.
