Fraternal
Identical twins are nature’s own human clones, only they share the same conception, uterus and birthday. Twins can help us understand nature and nurture through observing separated identical twins or just through their behavior in general. “Curiously twinning rates vary by race. The rate among Caucasians is roughly twice that of Asians and half that of Africans … In Western countries most twins are fraternal, and fraternal twins are increasing with the use of fertility drugs.” (Meyers 97) Fraternal twins are just like siblings that share a uterus and a birthday.
