monozygotic

Examples of monozygotic in the following topics:

• Cleavage of the Zygote

  • In the case of monozygotic twins (derived from one zygote), a zygote divides into two separate cells (embryos) at the first cleavage division.
  • Monozygotic twins can also develop from two inner cell masses.

• Nature vs. Nurture

  • Each of these traits is measured and compared between monozygotic (identical) twins, biological siblings who are not twins, and adopted siblings who are not genetically related.
  • Typically, monozygotic twins will have a high correlation of sibling traits, while biological siblings will have less in common, and adoptive siblings will have less than that.

• Genetic Basis of Intelligence and Learning

  • Conventional twin studies reinforce this pattern: monozygotic (identical) twins raised separately are more similar in IQ than dizygotic (fraternal) twins raised together, and much more than adoptive siblings.

• The Biopsychosocial Model of Health and Illness

  • The greatest single risk factor for developing schizophrenia, for example is having a first-degree relative with the disease (risk is 6.5%); more than 40% of monozygotic twins of those with schizophrenia are also affected.

• Autism Spectrum Disorder

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

• Genetic and Environmental Impacts on Intelligence

  • Conventional twin studies reinforce this pattern: monozygotic (identical) twins raised separately are more similar in IQ than dizygotic (fraternal) twins raised together, and much more than adoptive siblings.
