|February 23, 2012
Summary
Monozygotic twins exhibit differences in traits and diseases due to epigenetic factors. Advanced sequencing technologies help explore DNA methylation
Area of Science:
- Epigenetics and Genomics
- Twin Studies
- Disease Susceptibility
Background:
- Monozygotic twins share identical genes but can differ in phenotypes and disease risk.
- Environmental factors and epigenetic variations are thought to drive these differences.
- Recent studies present conflicting evidence on the extent of epigenetic variability between identical twins.
Purpose of the Study:
- To review recent findings on epigenetic variability in monozygotic twins.
- To highlight unresolved questions regarding epigenetics and twin discordance.
- To discuss future research directions using advanced sequencing technologies.
Main Methods:
- Review of recent high-resolution DNA methylation studies.
- Analysis of next-generation sequencing data for epigenome interrogation.
- Discussion of epigenetic modifications, particularly DNA methylation.
Main Results:
- Evidence suggests epigenetic variability contributes to twin discordance.
- Conflicting data exists regarding the extent of DNA methylation differences.
- Next-generation sequencing enables large-scale epigenome analysis.
Conclusions:
- Epigenetic modifications, especially DNA methylation, play a role in regulating complex traits.
- Further research is needed to fully understand epigenetic variability in twins.
- Advanced sequencing technologies are crucial for future epigenomic studies.

01:25Genetic Variation
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.

01:18Polygenic Traits
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

01:25Inheritance
Gregor Mendel's pioneering work on the principles of inheritance fundamentally transformed our understanding of how traits are transmitted from generation to generation. His experiments with pea plants laid the groundwork for the discovery of genes, discrete units within organisms that control heredity.
Each gene exists in pairs, and the combination of these genes from both parents forms an individual's genotype. This genotype is a blueprint of potential traits. Examples of genotype traits...

01:39Chromosomal Theory of Inheritance
In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”
02:03Law of Independent Assortment
While Mendel’s Law of Segregation states that the two alleles for one gene are separated into different gametes, a different question of how different genes are inherited remains. For example, is the gene for tall plants inherited with the gene for green peas? Mendel asked this question by experimenting with a dihybrid cross; a cross in which both parents are homozygous for two distinct traits resulting in an F1 generation that are heterozygous for both traits.
