Twin cities

Twin studies have been used to distinguish between genetic and environmental factors for many disorders in the general population including ectodermal dysplasia, Ellis-van Creveld, and anencephaly. This review focuses on genetic disorders affecting monozygotic, dizygotic, and conjoined twins to gain a better understanding of them. Many studies focus on twins because they have a nearly identical genome, which eliminates environmental factors. In case studies, the concordance rates in monozygotic twins

The evidence for genetic contribution to individual intelligence are (1) Family studies indicate that intelligence occurs in families, (2) Twin studies illustrate a greater link within identical twins in IQ than between non-identical, or fraternal , twins. This is true even when identical twins raised apart are contrasted with fraternal twins reared together. (3) Adoption studies suggest that adopted children are slightly comparable to their biological parents in intelligence. The focus here is

results in all these articles provides more clarity as to the cause and nature of this autoimmune disease. Research done by Dr Sophia Steer, supports the hereditary nature of RA. Twin studies done by her, show that genes contribute to the risk of RA. Dr Steer’s research did not only include studies on monozygotic (twins that share 100% of their genes i.e. identical

The latest manual of mental disorders (DSM-5) includes various changes in the Feeding and Eating Disorders chapter as a significant number of professionals diagnosing patients realized individuals were not fitting into certain criteria and therefore being labelled with EDNOS “Eating Disorder Not Otherwise Specified”.

In this paper, I will discuss the overall prevalent causes for Autism as well as the different variations and subgroups. People are familiar with other disorders such as Down syndrome or Trisomy 21. These types of disorders are discusses

So generally the MZ twins to DZ twins variance in the susceptibility to Anorexia nervosa AN is 58% to 76% ( Klump et al,2001),while the variance in susceptibility to Bulimia nervosa BN is 54 to 83% (Bulik et al,1998). Also there is another study named Developmental differences

Studies have been carried out to isolate the genetic factor and theory assuming people are born criminals due to genetic inheritance. The types of research that were carried out to test whether we inherit criminal genes which cause us to offend are twins studies (identical and fraternal), adoptees and family studies. Several attempts were made to test biological and genetic theories. A study of 3000 prisoners in London in 1910’s found a strong link between criminality of spouses and between children
