ANTH 1 Lecture Notes - Lecture 3: Meiosis, Mitosis, Gene Flow
Document Summary
Evolutionary synthesis: the addition of genetic inheritance to darwin"s theory of natural selection (1930s and 1940s) Recorded all characteristics of first generation and manually breeds the plants and records characteristics of next generations. Figured out how inheritance works (recessive and dominant genes) Gene: physical unit of inheritance: example: gene for blue eyes. Allele: subunit of a gene, one allele inherited from the father and one from the mother: each allele may be dominant, recessive or co dominant. Punnett squares: tt, tt are homozygous alleles, tt are homozygous recessive, tt are homozygous dominant, tt are heterozygous alleles. Phenotype is a trait you can see: example: brown hair, blue eyes. Eukaryotes have nucleus, genome housed inside them: humans are eukaryotic organisms. Types of eukaryotic cells: somatic: body cells, gametes: sex cells. Deoxyribonucleic acid (dna: watson and crick (1953) figured out the structure of dna and how they store so much information. Codes for amino acids (structural and regulatory proteins)
