Biology 3593B Lecture Notes - Lecture 14: Punnett Square, Chromosome, Genetic Marker
Document Summary
What is qualitative: category e. g. cystic fibrosis, o or 1; where it is one or the other, you either have it or you don"t e. g. purple elderflower or yellow elderflower. What is quantitative: bell curve distribution (normal) aka parametric testing, variables swimming speed and intelligence can distribute normally, there are two considerations: Q number something to measure genetic. T trait characteristic of phenotype. L loci position/location of gene. Qtl = g x e: one would create punnett squares for one locus, two loci and six loci; these are using mendelian models to explain quantitative traits: A), (b), and (c) show the predicted genotypes and phenotypes for parental, f1, and f2 longflower tobacco plants under mendelian models in which corolla length is determined by the alleles at one, two, and six loci. For two loci the ratio is 1/16, 4/16, 6/16, 4/16 and 1/16.
