Document Summary
Goal will be to connect mendel"s ideas with our other course content: review: mendel"s experiments and model, mechanism of dominance", meiosis and . Did cross breeding (outcrossing) instead of sel ng. Goal: wanted to test the blending theory- blending inheritance. If there is two copies of alleles are different (heterozygote), 1 is dominant and determines the phenotype. Variation is due to discrete, hereditary particles (genes) Individuals carry two copies of the genes. 2 copies segregate and enter gametes single(fertilization restores the 2 copies) Connecting vocabulary: homologous chromosomes carry genes, gene ex. eye colour, alleles ex. Blue eye colour: locus: location on a chromosome (loci-plural) Friday, october 24, 2014: phenotype: physical expression, genotype: genes. = p(p) x p(p) + p(p) x p(p) + p(p) x p(p) Connecting independent assortment: we can take all different assortments of the alleles. Morgan"s hypotheses: pr and vg genes are physically associated on the same chromosome.
