Sexually differentiated behavior has been shown to be affected by both genes and hormones. The discovery of the SRY gene, which codes for the development of testes, lead to the development of the Four Core Genotypes model of mice, and the separation of sex chromosomes and its resulting gonadal hormones. Using the FCG model, this study aims to look at the development of sexually differentiated behavior in mice, and track how it changes throughout their life. FCG mice will be divided into individual and social housing, and repeated experiments carried out to test their reaction to both intact female and male stimulus mice. The expected outcome is that the initial effect of the SRY gene on will fade with time and repeated experiments, and that it will fade quicker in socially housed mice.
