bros got more aggressive sperm.
normally one sperm gets into the egg and the egg locks out all latecomers soon thereafter.
However, w blacks, because the ladies all fuck all the time, they had more competitive sperm and so when one sperm makes it in another sperm is close behind it and gets in there too, before the egg membrane locks its doors. One kind of twin anyway. but nigs twin a lot more than other races because they have had a long history of unchaste inconstancy, as reflected in their whole reproductive systems on a microscopic level.
