Mendel observed the same pattern of inheritance in six other characters , each
represented by two different traits ( Table 14.1 , on the next page ) . For example ,
the parental pea seeds either had a smooth , round shape or were wrinkled .

Thus , a genetic locus is actually represented twice in a diploid cell . The two
alleles at a particular locus may be identical , as in the truebreeding plants of
Mendel's P generation . Or the alleles may differ , as in the Fj hybrids ( see Figure
14.4 ) ...

Thus , our breeding experiment represents an F1 dihybrid cross , like those that
produced a 9 : 3 : 3 : 1 ratio in Mendel's experiments . We can use a Punnett
square to represent the genotypes of the F2 offspring ( Figure 14.11 ) . As a result
of ...
