Thus, interfamilial phenotypic variation will be greater than intrafamilial variation. Researchers use sibling and twin studies, for instance, to estimate heritability of a phenotype, controlling for sources of variation such as major locus heterogeneity and environmental influence. In one such example, Vanscoy et al. compare lung function between monozygotic and dizygotic twin pairs, as well as siblings with cystic fibrosis (CF).

The first use of central tolerance was by Ray Owen in 1945 when he noticed that dizygotic twin cattle did not produce antibodies when one of the twins was injected with the others blood. His findings were confirmed by later experiments by Hasek and Billingham. The results were explained by Buret’s clonal selection hypothesis. Burnet and Medawar won the Nobel Prize in 1960 for their work in explaining how immune tolerance worked.

Born in São Luís, Phabullo is a dizygotic twin and has an older sister. Phabullo spent part of his childhood and adolescence living in the cities of Santa Ines and Caxias, both in the interior of Maranhão, due to financial difficulties. He never knew his father, who abandoned his mother, a nurse, when she was pregnant with him. During his childhood, Phabullo experienced bullying because of his delicate gestures and feminine voice.

A genetic component to the cause of UC can be hypothesized based on aggregation of UC in families, variation of prevalence between different ethnicities, genetic markers and linkages. In addition, the identical twin concordance rate is 10%, whereas the dizygotic twin concordance rate is only 3%. Between 8 and 14% of people with ulcerative colitis have a family history of inflammatory bowel disease. In addition, people with a first degree relative with UC have a four-fold increase in their risk of developing the disease.

That is, estimates of shared environmental effects (c^2) in human studies are small, negligible, or zero for the vast majority of behavioural traits and psychiatric disorders, whereas estimates of non-shared environmental effects (e^2) are moderate to large. From twin studies c^2 is typically estimated at 0 because the correlation (r_{MZ}) between monozygotic twins is at least twice the correlation (r_{DZ}) for dizygotic twins. When using the Falconer variance decomposition (1.0 = a^2 + c^2 + e^2) this difference between monozygotic and dizygotic twin similarity results in an estimated c^2=0. It is important to note that the Falconer decomposition is simplistic.

Sømme and Bonnevie published studies on polydactyly ('Postaxial polydactylism in six generations of a Norwegian family' in 1922), and twins ('Hereditary predisposition to dizygotic twin- births in Norwegian peasant families' in 1926). Upon hearing of the growing work being done by William Bateson on genetics at the John Innes Horticultural Institute (now the John Innes Centre) in the UK, Sømme wrote to Bateson requesting to join him working on Primula sinensis, crossing the North Sea in 1921, initially as a volunteer. During her time working in the 'Ladies Lab' with other female geneticists including Caroline Pellew and Dorothea De Winton, Sømme studied Primula sinensis genetics and cytology. The research she conducted at the John Innes Horticultural Institute formed part of her doctoral dissertation, which was finished in 1931.
