Parsons (1955) said females have an 'expressiverole' in the family - This is natural based on the fact they bear children - a role which is also then reinforced by socialisation
Parsons (1955) said males have an 'instrumentalrole' - the breadwinner & the protector - Also based on physical strength & reinforced by socialisation (these roles are functional for the family)
Parsons (1955) said the 'expressiverole' of females & 'instrumental role' of males are functional for the family & society
However, most sociologists argue that gender, and gender identities are socially constructed, learned through socialisation but also changeable (like Mead's stud where males & female behaviour is learned rather than biologically determined)
Willmott and Young (1962) were criticists of Parsons (1955) Functionalist View on Gender
Willmott and Young (1962) argue men & women now take greater share of domestic tasks and women are wage earners (this rejects Parsons, 1955 Functionalist View on Gender)
