Question 11

One researcher,Gregor Mendel,studied the genetics of pea plants related to flower colors,pea colors,pea pod shapes and other features of the plant.He numerically modeled the results he observed and published results,which eventually led to our basic understanding of how biological traits are passed to new generations of organisms.This was before biologists had even identified DNA and chromosomes.His work,however was largely rejected for over thirty years,partly for minor record-keeping errors,and partly for the new approach of defining reproduction of organisms in terms of numerical probabilities.This demonstrates that
