Study Notes
The Physical Self
- Our physical self encompasses appearance, how we see ourselves in the mirror, and initial impressions others have of us.
- It also includes the biological processes behind our physical features.
- Physical characteristics like height, skin color, and hair color aren't random; they're determined by genetic transformations and biological development.
Heredity
- Traits are passed down from parents through genes.
- Genes are the fundamental units of heredity.
- Genotype is the information within a gene.
- Phenotype is the observable expression of a trait.
- Genotype doesn't always guarantee a visible/observable phenotype.
Chromosomes
- Each person has 23 pairs of chromosomes.
- The 23rd pair determines sex (XX for female, XY for male).
- Chromosomes contain genes, stored within the cell's nucleus.
- Deoxyribonucleic acid (DNA) carries genetic instructions for physical traits.
Maturation
- Development and growth from birth to adulthood, culminating in physical changes.
- Involves the completion of genetic characteristics and unlocking of potential.
Environment and the Physical Self
- Our genetic predispositions aren't the sole determinants of our physical development.
- Environmental factors, like social networks, societal expectations, and cultural practices, significantly shape our physical self.
- Family plays a key role in personal hygiene and nutrition.
- Socioeconomic status influences development.
- Cultural factors affect physical traits and diets.
- East Asian cultures often emphasize rice as a primary carbohydrate source, while Western cultures don't.
