In addition , mutations were also found in mothers of dizygotic twins .

Dizygotic twins arise from two separate eggs fertilized by two spermatozoa .

Whereas identical twins develop from one embryo that splits in half , dizygotic twinning thus starts with a multiple ovulation .

与之相反，同卵双胞胎是由一个卵细胞一分为二发育而来的，因此异卵双胞胎的起因是超数排卵。

Non-identical twins , medically known as dizygotic , develop from two separate eggs from separate follicles fertilised by separate sperm cells .

医学上定义的异卵双胞胎，是指两个不同卵泡中单独的两个卵子，和两颗精子结合发育而成。

A trait or disease is called heritable if monozygotic twins are more similar to each other than dizygotic twins .

如果一种性状或疾病在同卵双胞胎中的同时发生的概率高于异卵双胞胎，那么这种性状或疾病是“可遗传的”。

Discovery of the main genes behind the mystery of spontaneous dizygotic twinning was long awaited , and is of great scientific interest and clinical importance , ' said Professor Boomsma .

博穆萨教授表示：“人类早就希望能解开自发性异卵双胞胎的秘密，这一直是科学界和临床研究中重要的课题。”

And then there was Layton , my dizygotic twin .

Results : In the Study One , we totally collected eligible 1311 pairs of twins , 908 Monozygotic twins ( MZ ) and 403 Dizygotic twins ( DZ ) .

结果：在遗传因素对原发性痛经影响的研究中，共收集到合格的双胞胎共1311对，其中同卵双生子908对，异卵双生子403对。

Of , relating to , or being a twin developed from two separately fertilized ova ; dizygotic . Monozygotic twins , on the other hand , arise from the same fertilized egg .

同卵双生子则是由同一个受精卵发育而成的。

Methods One hundred and forty-three healthy monozygotic ( MZ ) twin pairs and 93 dizygotic ( DZ ) ones aged 5 to 19 [ with a mean of ( 11.2 ± 3.4 ) years ] .
