Sperm faulty in prader
genes has been "turned off", or imprinted, and the remaining gene is defective? gene is thought to occur during the formation of an egg or a sperm cell. sort of genetic imprinting, including Angelman syndrome, Prader-Willi syndrome.
Research on Birth Defects Shifts to Flaws in Sperm
Description:On the other hand, a better outcome for the mother's genes would be for all of her kittens to survive to adulthood and reproduce. But they are reset during egg and sperm formation. Dolly the sheep was the first mammal to be cloned by somatic cell nuclear transfer SCNT. In some species, more than one male can father offspring from the same litter. Heart defects would be a common outcome of exposure to the chemical. This conflict of interest sets up an epigenetic battle between the parents -- a sort of parental tug-of-war. Some of the important genetic characteristics of PWS identified through research are:
