... After meiosis (sexual reproduction), the genetic traits of an organism are segregated and readied to be passed from parent to offspring. When sexually reproducing organisms undergo meiosis, they produce gametes that are haploid (n). Haploid cells include sperm and ovum (unfertilized egg) that have h ...

The clustering of these escapees in domains in the recently added layer of the X suggests that the process lags behind Y degradation and i ...

X-inactivation



X-inactivation (also called lyonization) is a process by which one of the two copies of the X chromosome present in female mammals is inactivated. The inactive X chromosome is silenced by its being packaged in such a way that it has a transcriptionally inactive structure called heterochromatin. As nearly all female mammals have two X chromosomes, X-inactivation prevents them from having twice as many X chromosome gene products as males, who only possess a single copy of the X chromosome (see dosage compensation). The choice of which X chromosome will be inactivated is random in placental mammals such as humans, but once an X chromosome is inactivated it will remain inactive throughout the lifetime of the cell and its descendants in the organism. Unlike the random X-inactivation in placental mammals, inactivation in marsupials applies exclusively to the paternally derived X chromosome.
