WebJan 23, 2004 · Johannsen's distinction between genotype and phenotype, was however, induced, not by Weismannism, but by the rediscovery in 1900 of Mendel's work on inheritance in the garden pea. The critical feature of Mendel's result was the result he obtained in the first and second generations of crosses between pea plants with clear-cut … WebMendel generalized the results of his pea-plant experiments into four postulates, some of which are sometimes called “laws,” that describe the basis of dominant and recessive inheritance in diploid organisms. As you have learned, more complex extensions of Mendelism exist that do not exhibit the same F 2 phenotypic ratios (3:1).
