Williams syndrome affects both men and women equally, as it is caused by a deletion of genetic material on chromosome 7, which occurs randomly during the formation of reproductive cells. This genetic anomaly is not linked to sex, so the prevalence is similar across genders. Overall, the incidence of Williams syndrome is approximately 1 in 7,500 to 1 in 20,000 births.
No. Older women are more likely to have Down Syndrome babies. The risk is highest after age 35.
No race is more likely to spontaneously have issues with meiosis, and as Klinefelter's is not hereditary (anyone with it is infertile and cannot pass on genes) no race will become more likely to have Klinefelter's syndrome. The population of older women who have children is more likely to have Klinefelter's babies. Older women are less likely to miscarry a baby with a chromosomal defect, so more Klinefelter's babies are born to them.
Women
Nope
Heart problems are more common in women with Turner syndrome, although I do not know if I would say they are the norm.
down's syndrome is more likely
women.
Marfan syndrome affects men and women of all ethnic backgrounds equally.
Women are more often bitten by cats
yes they will have one more chromosome
Unless one has translocation (inherited) Down syndrome than No, they more than likely Won't.
