We can apply the same reasoning to an Fı monohybrid cross ( Figure 14.9 ) . With
seed shape in pea plants as the heritable character , the genotype of Fı plants is
Rr . Segregation in a heterozygous plant is like flipping a coin : Each egg ...

To figure out the probability that an F2 plant from a monohybrid cross will be
heterozygous rather than homozygous , we need to invoke a second rule . Notice
in Figure 14.9 that the dominant allele can come from the egg and the recessive ...
