Dizygotic twins, or fraternal twins, can "run in families", but only through the woman's side, as a double ovulation is required for fraternal twins to be conceived. As mentioned above, if a woman is taking fertility drugs or undergoing IVF, fraternal twins are also probable. Dizygotic twins are conceived when two separate ova are fertilized by two separate sperm. As a result, fraternal twins can be same sex or opposite sex. There is even the remote possibility that fraternal twins could have different fathers (such cases have been documented). Dizygotic twins develop in the uterus seperately, each in their own chorion (outer sac, connected to the placenta) and amnion (inner sac, containing the amniotic fluid). Dizygotic twins each have their own placenta, though if they implant in the uterus close together, it may appear on an ultrasound as one placenta, because the placentas have fused together.

Daily Literature Deviations is a group that is dedicated to bringing literature to the forefront of the deviantArt community. We attempt to accomplish this by daily featuring Literature artists from around the community that deserve the recognition, but are not getting it.
Each day we will feature 5 deviations from the Literature categories in a News Article. In order to support the artists that we feature, we ask that you the news article as well as check out the individual pieces. We understand that each day you may not be able to check out each and every one of the pieces, everyone has their own things going on. We just ask that you make an attempt to help support the growing Literature community.
