Discuss the roles of hormones and genes in gender development
Everyone has 23 pairs of chromosomes and of these one set of sex chromosomes and these establish our sex. Females have XX chromosomes whereas males have XY chromosomes. Although the Y chromosome doesn’t carry much genetic information it does determine an individual’s sex, this causes changes to the embryo from a very early stage. Usually there is a direct link between our chromosomes and our internal/ external reproductive organs. It is these chromosomes that stat a chain of events that establish the individuals sex.

Chromosomes determine a person’s sex but most gender development is actually governed by hormones. Hormones are released prenatally and in adolescence when we

Deady et al did research into this and found higher testosterone levels were associated with lower measures of maternal personality and reproductive ambition. Participants who scored highly on masculinity had higher levels of testosterone. This supports the theory as it shows that higher levels of testosterone (a hormone) has a relationship with the brains development.

The study can be evaluated as it’s a correlational study it’s difficult to establish a clear cause and effect this makes the study less valid to support the theory.

The theory its self is reductionists as it only looks at one factor, it focuses on the biology and ignores other elements such as environmental factors. This can strengthen the study as it makes it easier to be treated and explained but as it ignores other factors it may not be finding the true causes and other impacting variables.

The theory is also deterministic as it ignores the individual’s free will, this gives them no choice over there gender and takes the blame away as it’s already pre-determined by their biology and they can have no impact.

Discuss the evolutionary explanations of gender roles
The evolutionary explanation focuses on gender roles, the attributes each sex adopts. It suggests that we have adapted these gender roles as a survival instinct, these roles help to ensure our breeding and the survival of our genes and species. Changes in behaviour and physical appearance occur through mutation. Although
