Topics in Heredity
1
Variation and Reproduction
- Reproductive processes create individuals that are similar but subtly different
- Asexual reproduction produces limited variations due to small DNA copying errors
- Sexual reproduction maximizes successful variations and creates greater diversity
2
Mendel's Laws of Inheritance
- Gregor Mendel studied inheritance patterns in pea plants
- Both parents contribute equal amounts of genetic material to offspring
- Each trait is controlled by two factors (genes) - one from each parent
3
Genetic Basis of Inheritance
- DNA contains information for making proteins that control traits
- Genes are sections of DNA that code for specific proteins
- Proteins (enzymes, hormones) determine observable characteristics
4
Sex Determination
- Different species use different methods for sex determination
- Some species rely on environmental factors (temperature in reptiles)
- Some organisms can change sex during their lifetime
