Study Notes
DNA and Genetics Lesson Summary
- Lesson objectives include identifying DNA components and bases, predicting DNA strand patterns, and understanding DNA double helix parts
- Genes are DNA segments encoding heritable traits, while alleles are two forms of the same gene inherited from parents
- Genotypes describe an organism's allele pair, while phenotypes describe the expressed trait
- Cat coat color genetics are used to explain purebred and hybrid traits inheritance
- Punnett Squares are used to predict inheritance probabilities for dominant and recessive traits
- Patterns of inheritance include complete dominance, incomplete dominance, and co-dominance
- Continuous traits in dogs involve multiple gene pairs and allele combinations
- Most inheritance patterns are complex and influenced by environmental factors
- DNA is compared to a book, with genes as sentences and chromosomes as chapters
- Environmental factors such as trauma, nutrition, and toxins greatly influence expressed traits
