Episode notes
Mendel's Foundational Genetic Laws
- Mendel's laws of segregation, independent assortment, and dominance laid genetic foundations despite exceptions.
- These laws explain gene pair inheritance, independent trait sorting, and dominant allele expression.
Darwin's Natural Selection Insight
- Darwin's natural selection favors organisms producing more offspring, not just longer survival.
- Evolution involves species divergence due to genetic variation and environmental adaptation.
Human Chromosomes and Ploidy
- Humans have 23 chromosome pairs, totaling 46 chromosomes; each consists of two sister chromatids during cell division.
- Ploidy denotes sets of chromosomes: humans are diploid, carrying two sets from each parent.
