Can identical twins be different genders? In 999% of cases boy/girl twins are non-identical However, in some extremely rare cases resulting from a genetic mutation, identical twins from an egg and sperm which began as male (XY) can develop into a male / female pair
Which race is most fertile?
By 1990, the fertility trends show three distinct groups defined by race and education: less educated blacks have the highest fertility (TFR = 22–24), educated whites and blacks have the lowest fertility (TFR = 16–18) Less educated whites have fertility levels between these two groups (TFR = 20–21)
Can you have a white and a black twin?
British researchers calculated that the odds of two sets of “black and white twins” in the same family are about 2 in a million Though the Durrant-Spooner family makes for an extreme example, the dissimilarities in the children are no different from the distinct characteristics you’ll see in any siblings

Superfecundation is the fertilization of two or more ova from the same cycle by sperm from separate acts of sexual intercourse, which can lead to twin babies from two separate biological fathers The term superfecundation is derived from fecund, meaning the ability to produce offspring

The result is two separate pregnancies happening at the same time It’s such a rare occurrence that medical experts have only been able to identify a few confirmed cases of superfetation in pregnant women So, while yes, you could get pregnant while you’re already pregnant, it’s probably not something to worry about
How can I sleep with my husband during pregnancy?
- Side-lying positions: Lying on your side is often the most comfortable, whether you’re facing front-to-front or front-to-back
