They suggest the answer lies in epigenetics, or how the expression of genes is controlled by ‘temporary switches’, such as how a gene behaves, known as epi-marks.
Gender-specific epi-marks are usually ‘erased’ from generation to generation, but when they do not and they pass from a parent to a child, it can result in homosexuality.
