The cause of disease of grape foetus

The real outbreak of grape foetus contains not clear reason.The case checks against the occurrence that the research discovers a grape foetus to have something to do with nourishment condition, social economy and age.The cause of disease learns middle age age is on showing a Zhao related factor, the age is older than the 40 years old grape foetus incidence rate is taller than young women 1000%, the age is younger than to add year old is also the high Wei factor that takes place a completeness grape foetus, these two age stage the women easily have already conceived blemish.Parts of sex grape foetus has nothing to do with the pregnant woman age.
Combines a pathology research to prove two types of grape foetuses each the characteristics with genetics through a cell genetics.The chromosome gene set of completeness grape foetus is a paternal source, namely the ovum checked imperfection or egg at first in the egg the pit developed formation after losing the live circumstance the bottom checked to combine at first with Jing at first.The chromosome checks the type as 200% bodies, among them 90% is 46, the XX is conceived by an empty egg(have no gene material egg) and a monoploid sperm(23, X), through oneself replication instauration is 200% bodies(46, XX), the rebirth grows growth but become, be called empty the egg conceive.Minority of of its pits type is 46, XY, these are two personality chromosome different sperms(23, X and 23, Y) in the meantime the then empty egg conceive and be called a pair of sperms to conceive.Parts of sex grape foetus pit type is often a triple body, 80% is 69, XXY, rest is 69, XXX or 69, XYY, come from a father square chromosome composition that the normal ovum and double sperm conceives and bring a set of surplus from here;Can also go together with son to combine because of 2 times bodies of a normal monoploid ovum(or sperm) and meiosis failure to.
