Twins are common on my both my fiancés mom and dad’s side and on my dad’s side what are my chances of having twins?

If you have a mother,

If you have a mother, brother, sister, uncle or long lost cousin with multiples, you may wonder if you'll have them too. Sometimes twinning is hereditary, though only fraternal (dizygotic twins are influenced by heredity, and then only in some cases.

If your mother or maternal grandmother was or had fraternal twins, you might have inherited a gene for hyperovulation, increasing your chances of conceiving twins also. When conceiving twins, hereditary history on the father's side is not thought to have an impact.

Older mothers are much more likely in conceiving twins. African-American women are more likely to conceive twins than Caucasian women, and Asian women have the least chances of having twins.
