Parthenogenesis occurs when embryos are formed without fertilization. Copperheads are capable of a special type of reproduction called facultative parthenogenesis, where the snake switches from sexual to asexual. This form of reproduction creates a diploid zygote, which contains two sets of chromosomes. This process seems to be a specific characteristic of pit vipers -- of which the copperhead is one -- but research shows the phenomenon may be more common.
