Know these terms on extensions to mendel"s laws slide. even with peas, results did not fit perfectly always. not everything fits with mendel"s proposed 3:1 ratio. . so, perhaps understandable that mendel was ignored: 3:1 sometimes achieved. 1 camp mendel are not universally applicable. advocated that mendel discovered something key, fundamental. different ratios in progeny then these ratios can be explained and still apply. Mendel"s law of independent assortment and equal segregation. accumulation of cholesterol in the skin severe effect: 3 phenotypes in f. both alleles are expressed in heterozygote no intermediate phenotype. Level of genotype codominance both are there. 1:1 ratio red must be rr; etc. No inherent nature to whether codominant, or incompletely dominant. can have codominance at one level, and dominance at another level, etc. ex. at phenotype level, incomplete dominance, but codominance at the protein level.
