Discuss research evidence into the role of genes and hormones in gender development
Gender development can be explained by biological influences which includes hormones and genes.
The base line of biological influences in gender development is that biological sex is determined by sex chromosomes, XX for female and XY for males. But this approach also argues that genes and hormones are the main influence on gender roles and gender identity in gender development. A research by Ridley has found out that biological sex is determined by a single gene called SRY gene and argued that it also ultimately determines the gender roles and gender identity. When SRY gene is present and functioning normally then this will result in a male otherwise in a female.
SRY gene switches another gene called SOX9 which switches other genes that masculine the brain and the body by controlling the release of hormones including the most important hormone the androgen testosterone. SRY gene determines both biological sex and gender in gender development, in rare cases where an XY male has a mutant non-functioning version of the SRY gene they will develop into normal fertile woman who develops female gender roles and female gender identity.
In another study using genetic engineering, a female XX mice have been injected with an SRY gene into their embryo. It was found that they have developed into males that demonstrated normal male sex role behaviours.
SRY genes researches provide valuable insights into how biology influences out gender development. It demonstrates how our gender is determined through the level of hormones that interact with our biological sex. Also the psychologists argue that SRY gene plays an important role in our gender development which includes gender identity and gender roles, therefore the biological approach can claim to have good face validity because it is testable and reasonable but also empirically supported explanation of gender development.
Although Ridley's explanation of gender roles, gender identity and biological sex provides valuable
