While I was still in high school, I knew two sets of boy twins; and this was in a small town. One set of twins was in my class, and the other set was 2 years behind me. In fact, one set was identical twins.

I had no idea the entire world consisted of only people you can personally see.

??? What statistics have you been reading??? "Every pregnant woman (by implication, across the world) who has twins...." How many women pregnant with twins have you seen? 3, 6, 15? Ah. yes, I thought so.

They are not. Twin types and genders are oddly symmetrical. 1/3rd of all twins are identical, 1/3rd are the same sex fraternal and 1/3rd are male/female fraternal. Of the identical twins, half are male/male, and half are female/female. Of the same sex fraternal, half are male/male, and half are female/female.

it's based on the males chromosomes, so can be male, female, fraternal, or identical
