Consider the work Mendel did with his pea plants. Why is the study of human genetics much more
difficult? What will be an ideal response?
Compared to peas, humans are a difficult species on which to perform genetics. First, we have a long
generation time making studies of the multiple generations difficult. Second, we produce relatively
few offspring which weakens statistical analysis. Third, we can’t ethically be told who to mate with so
controlling crosses is difficult. Fourth, we can’t self-fertilize. Fifth, many of our traits do not follow
simple Mendelian inheritance patterns. The list goes on and on.
