Dizygotic twins: Twins derived from two different eggs. Often called fraternal twins.
Dysplasia: Abnormal, precancerous changes in the cells of the cervix.
Dysuria: Difficulty or pain urinating.
Dizygotic Twins - See "Fraternal Twins".
Dominant Disorders - Genetic disorders transmitted from parent to child in which a single abnormal gene overrides the normally functioning gene.
Dizygotic Twin - The most common type of multiple pregnancy. Fraternal twins occur when two different eggs are fertilized by different sperm.
Dizygotic twins (fraternal twins)
A twin pregnancy most commonly occurs when two separate eggs are fertilized by separate sperm to form two zygotes. Each zygote implants in the uterus individually and develops its own membranes and placenta.
In dizygotic, or "fraternal," twins, not only maternal age, but the number of previous pregnancies ("parity"), increases the chances of twins.
FACT: Dizygotic or two-egg twinning passes down the female line from generation to generation.(1)
IMPACT: An expectant mother may disregard her symptoms of a multiple pregnancy, because she believes that she can't have twins since her mother did.

Fraternal twins are referred to as dizygotic twins, meaning that two unions of two gametes or male/female sex cells occurred to produce two separate embryos. Characteristically, with fraternal twins, each has its own placenta and amniotic sac.
There are two types of twin pregnancies, identical or monozygotic twins and fraternal or dizygotic twins. Identical twins are conceived from a...

There are two types of twins: monozygotic (identical) and dizygotic (fraternal). Identical twins result from the duplication of cells in the early stages of development.

Fraternal twins, also known as dizygotic twins since they come from two eggs and two sperm, always have their own placenta and surrounding sacs.
Non-identical twins (also called fraternal, dizygotic, DZ or binovular) are no more alike than any other brothers or sisters.
Fraternal twins (also called dizygotic twins) develop when two separate eggs are fertilized by two different sperm. Each twin usually has its own placenta.
Multiples: If two eggs are released from the ovary (or one egg from each ovary) and are fertilized by two separate sperm, fraternal twins (dizygotic) have been conceived.
Fraternal twins are also referred to as dizygotic which results when two eggs are fertilized by two sperm. These twins may or may not look alike and really only are two siblings who share the same uterine growing space.
Two-thirds are non-identical or dizygotic twins (when two eggs are fertilised by different sperm). The chance of any woman having identical twins is one in 300.
Twins that not genetically identical, also called dizygotic twins. When women ovulate two different eggs and they are fertilized at the same time by two different sperm the result is fraternal twins.
There are two types of twins - identical (monozygotic) and fraternal (dizygotic). To form identical twins, one fertilized egg splits and develops two babies with exactly the same genetic information.
Identical twins are also called monozygotic while fraternal twins are known as dizygotic. Fraternal twins usually develop in separate amniotic sacs and have separate placentas. Identical twins share the same amniotic sac but have separate placentas.
boys, while those with long follicular phases tended to produce girls. This relationship is consistent with other data and could explain sex-related differences in the length of gestation and the observed excess of same-sex pairs among dizygotic ...
