Genes that are on the same chromosome, or linked, do not assort independently, but can be separated by recombination. Describe how recombination can separate linked genes. Two genes close together on the same chromosome tend to be inherited together and are said to be linked.
How do twin studies work? Most twin studies involve comparing pairs of identical and non-identical twins. Identical (called 'monozygotic') twins come from the same egg, so they share all of their genes - this is why they look so similar. Non-identical ('dizygotic') twins come from two different eggs, even though they shared their mother's womb and were born at the same time.
