Some turkeys (and chickens) reproduce without
sex. Parthenogenesis is reproduction without benefit of sex. In
other words, asexual reproduction in which the offspring develops
from unfertilized eggs. It occurs spontaneously in a handful of
species, like insects, lizards, snakes, and sharks. Turkeys have a
virgin birth rate in some breeds of up to 40 percent. Virgin birth
can become more frequent in turkeys if the female is exposed to
semen having a low sperm count.
