Psychologists believed that all children struggle to create a separate identity, but she suggested that western individualistic males struggle more than relationship-oriented females
59
How do female and male brains differ?
There are no striking structural sex differences, but the female brain is wired in a way that better enables social relationships
60
How does biology influence sexual development
Through our genetics, our differing sex chromosomes. And physiologically due to the different concentrations of sex hormones which trigger other anatomical differences
61
What is the female chromosome and what is the male chromosome?
XX for female, XY for male
62
What may occur at 7 weeks in the womb
If the embryo has a Y chromosome, a gene will become active that triggers the testes to develop and produce testosterone

What are effects of sex hormones on 3 different parts of life?
- prenatal period, directs sexual organ development based on which one is present in excess
- puberty, sex hormones triggers adolescence
- after puberty and well into the late adult years, sex hormones facilitate sexual behavior
81
How do women respond to testosterone levels?
Testosterone levels affect sex drive of women. Low levels mean little drive and high levels mean high sex drive

no
91

102
What role do hormones play during the second trimester
Exposure to certain hormones can predispose the embryo to exhibit gender-atypical traits and sexual orientation. Example being a female being expose to testosterone can predispose her to have same-sex attraction
103
What is the older brother or fraternal birth order effect and why does it occur
Men with older brothers are more likely to be gay. The assumed reason being that male fetuses stimulates the mother to produce antibodies that become stronger with each passing boy, resulting in the preventing of the male fetus brain developing in a male typical pattern
