Summary of mendel"s work: both parents contribute equally, inheritance is particulate not blending, there are two copies (alleles) of each gene associated with a given trait, gametes contain one copy of the gene, alleles segregate randomly, alleles are dominant or recessive, different pairs of alleles segregate independently. Rediscovery of mendel: mendel"s work was unappreciated and remained dormant for 34 years, even darwin"s theories were viewed with skepticism in the late 1800"s because he could not explain the mode of inheritance of variation, in 1900, 16 years after mendel died, three scientists rediscovered and acknowledged mendel"s work, giving birth to, 1900 carl correns, hugo devries, and erich von tschermak rediscover and confirm mendel"s laws, most traits in humans are due to the interaction of multiple genes and do not show a simple mendelian pattern of the science of genetics.
