Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in organisms. Research published on January 7 in the journal Nature Genetics shows that identical twins differ by an average of 5.2 genetic mutations. It would be more likely for a genetic anomaly to either cause both ovaries to produce an egg each cycle, or all embryos to split and produce twins, or quads.

Thus, cells from two clones have the same DNA and the same genes in their nuclei. As identical twin pairs share the same genetic background, similarities in twins from a pair result from either shared genetic or shared environmental factors, although the influence of shared environmental factors (e.g. The goal of mitosis is to produce two daughter cells that are genetically identical to the parent cell.
