Genetic mutations that boost individual's adaptability have greater chances of getting through to X chromosomes
One of the most important questions for evolution researchers is how a species develops and adapts during the course of time. An analysis of the genes of twelve chimpanzees has now demonstrated that the chimpanzee X chromosome ...

X chromosome
The X chromosome is one of the two sex-determining chromosomes in many animal species, including mammals (the other is the Y chromosome). It is a part of the XY sex-determination system and X0 sex-determination system. The X chromosome was named for its unique properties by early researchers, and this resulted in its counterpart being named the Y chromosome for the next letter in the alphabet when it was discovered later.
