Problem set 1 posted on ctools (use the key to check your answers). 5. a multiple alleles and multiple types of dominance. Mendel worked with simple traits controlled by single genes and only analyzed crosses involving two alleles of those genes where one allele showed complete dominance to the other. In reality, many more than two alleles of a gene are usually found within a population; when this occurs, we say that a gene has multiple alleles. Read subsection 16. 5. 3 ( many genes have multiple alleles ) for a few examples of multiple alleles in humans.
