dizygotic twins

However, dizygotic twins may also look very different from each other.

Like any other siblings, dizygotic twins may look similar, particularly given that they are the same age.

Women who have three or more children are also likely to have dizygotic twins.

Dizygotic twins, like any other siblings, have an extremely small chance of having the same chromosome profile.

In a recent study using monozygotic and dizygotic twins, genetic evidence was given for a general factor of personality.

Neither result was seen to a similar degree in dizygotic twins, offering strong favour for high genetic aetiology.

The concordance is around 20% for dizygotic twins.

In one study on humans, the frequency was 2.4% among dizygotic twins whose parents were involved in paternity suits.

Dizygotic twins have a 23% concordance rate.

Unfortunately, though he knew about mono and dizygotic twins, he did not appreciate the real genetic difference.

Dizygotic twins are also more common for older mothers, with twinning rates doubling in mothers over the age of 35.

Dizygotic twins were always two zygotes.

From a biological point of view, the differences in these fraternal or dizygotic twins from two biracial parents are not surprising.

In addition, research suggests that there is a much higher concordance rate among monozygotic twins compared to dizygotic twins.

Monozygotic twins have double concordance rate for hysterectomy compared to dizygotic twins.

Most often it is estimated by comparing monozygotic and dizygotic twins [ 34 ] .

These reports indicate concordance rates of over 50% for monozygotic twin pairs compared with under 10% for dizygotic twins.

Researchers have used this method to investigate genetic correlates of musical pitch recognition in both monozygotic and dizygotic twins.

Concordance rates between monozygotic twins was close to 50%; whereas dizygotic twins was 17%.

By analogy with monozygotic and dizygotic twins, such a combination is called dizygotic triplets.

In vitro fertilization (IVF) techniques are more likely to create dizygotic twins.

Monozygotic twins are more likely to be alcoholics and to develop liver cirrhosis than dizygotic twins.

Genetic factors also seem to play a role, as the concordance rate is two times higher in monozygotic twins than in dizygotic twins.

In it, Vonnegut and his sister transform into Swain "Neanderthaloid" dizygotic twins.
