HLTB20H3 Lecture Notes - Lecture 3: Homologous Chromosome, Genetic Recombination, Botany
Document Summary
Lecture 3: the basis of inheritance: the basics of human genetics. Amateur botanist who experimented with pea plants. He used very simple mathematics too simple so it cant be true. Well controlled botanical experiments, that just happened to have simple mode of inheritance. No physical evidence for heritable factors (cellular structures and their functions were. Comment [ag1]: not all plants or species use simple mode of inheritance just being discovered) Origins of the study of genetics not the study of chromosomes/genes, but the study of. If that characteristic is inherited believe it is influenced by genetics (genotype) phenotypes. Gene = the segment of dna molecule that codes for a single polypeptide chain: polypeptide chain a chain of amino acids. Allele = allelomorphs = alternative forms of a gene occupying the same locus on a. Comment [ag2]: actual term homologous chromosome 46 chromosomes in total 23 pairs. Through controlled pollination, observed changes in pea phenotypes from generation to generation.
