Two plants that both show the dominant characteristic produce an offspring with genotype bb. Which conclusions follow? Select all that apply.

Explicación

An offspring takes one allele of the gene from each parent, so a pair of recessive alleles can only be assembled when both parents had one available to give. Since these two plants show the dominant characteristic while each of them holds a recessive allele, each must hold one allele of each kind, and neither of them has to show the recessive characteristic for such an offspring to appear.
