This statement is true. Non-identical or fraternal twins occur when a woman releases two eggs and both eggs are fertilized by separate sperm. This can be a genetic tendency in some families. Identical twins, on the other hand, occur when a single fertilized egg splits into two embryos. While there may be a family tendency for fraternal twinning, there is no genetic influence on identical twinning. Thus, option A is incorrect. Option C is false as identical twins are not rare, but occur in about 1 in every 250 pregnancies. Option D is also incorrect as there is scientific evidence supporting a genetic influence on fraternal twinning.
