Of 5,597 monozygotic twin pairs where both were alive and had provided usable responses to CFS screening questions, we identified 140 pairs of twins who met preliminary inclusion criteria: born 1935-1985, classified as a monozygotic twin based on questionnaire responses ❋ Andrea Byrnes Et Al. (2009)
Therefore although I might call them "monozygotic" I wouldn't agree that they were "identical." ❋ 1 Dinosaur (2007)
In "A Genetic Study of Male Sexual Orientation," a study that has now achieved almost as much renown as LeVay's, the Northwestern University psychologist Michael Bailey and Boston University's Richard Pillard compared fifty-six "monozygotic" twins (identical twins, from the same zygote, or fertilized egg), fifty-four "dizygotic" (fraternal) twins, and fifty-seven genetically unrelated adopted brothers. ❋ Unknown (1997)
And most of us have probably ingested meat and dairy products from livestock cloned by natural reproduction (monozygotic siblings), mechanical embryo-splitting or even nuclear transfer from an embryonic donor cell into an enucleated oocyte. ❋ Henry I. Miller (2010)
In the switched-baby cases Ms. Segal discusses, it is highly unlikely that the error would have been discovered were it not for the fact that the twins were monozygotic and thus had a striking physical resemblance. ❋ David Cesarini (2011)
Classical liberals (libertarians, basically) accept that only monozygotic twins are “created equal” and that even these will diverge as they mature. ❋ Unknown (2010)
But births of monozygotic twins are rare, roughly one in 300. ❋ David Cesarini (2011)
The mother assumed that she had given birth to fraternal twins (dizygotic, from two eggs) and not "identical" ones (monozygotic, two embryos developed from a single fertilized egg). ❋ David Cesarini (2011)
In this article, we report the results of two independently conceived and executed studies of monozygotic and dizygotic twins, one in Sweden and one in the United States. ❋ Unknown (2008)
One thousand and seventy three pairs of adult monozygotic (MZ) twins and 895 pairs of same sex adult dizygotic (DZ) twins from the United Kingdom (UK) completed the Humor Styles Questionnaire: a 32-item measure which assesses two positive and two negative styles of humor. ❋ Unknown (2008)
Yesterday I blogged about a remarkable Finnish twin study, in which the investigators went to the considerable trouble of finding monozygotic twin pairs who showed marked differences in body weight. ❋ Unknown (2008)
In contrast, we present here evidence for cognitive “specialist genes”: monozygotic twins are more similar than dizygotic twins in the specific cognitive ability of face perception. ❋ Unknown (2010)
Each of three measures of face-specific processing was heritable, i.e., more correlated in monozygotic than dizygotic twins: face-specific recognition ability, the face-inversion effect [2], and the composite-face effect [3]. ❋ Unknown (2010)
First-degree female relatives and monozygotic twin offspring of patients with anorexia nervosa have higher rates of anorexia nervosa and bulimia nervosa. ❋ Aimee Liu (2010)
