The seven traits that Mendel studied in pea plants have a relatively simple pattern of inheritance. Since the time of Mendel, however, scientists have discovered many traits that have more complex patterns of inheritance. Which of the following elements from Mendel’s model of inheritance turned out to be oversimplifications that aren’t true for many traits? Check all statements that are oversimplifications. a. Parents do not transmit physiological traits directly to their offspring. Rather, they transmit coded information that controls the traits.
b. Each trait in an organism is controlled by one pair of alleles.
c. At each gene locus there are two possible alleles, one that is dominant and one that is recessive.
d. Genes may exist in alternative forms called alleles.
e. Each pair of alleles controls one trait.
f. When a diploid individual produces gametes, assuming no mutations or mistakes occur during cell division, the two alleles at a given gene locus segregate and each gamete receives only one of the two alleles.
