Day 18 - Whatever tickles your fancy

Today, I thought I would share some interesting twin facts.

1. Fraternal twins can be hereditary, but identical twins are just a fluke of nature.

2. Genetically speaking, the children of identical twins are half-siblings rather than cousins. If each member of one set of identical twins marries one member of another set of identical twins then the resulting children would be genetic full siblings.
