Question:
A pea plant has alleles for the dominant tall gene (T) and the recessive short gene (t). Therefore, it appears as Tt. Which of the following will correctly describe its phenotype if there is complete dominance? And which describes incomplete dominance? (complete, incomplete)
A
Tall, Average.
explanation
Because the dominant allele is present, this pea plant will be tall despite its recessive gene in complete dominance. In Incomplete dominance however, the gene must be homozygous to show one trait. Otherwise the phenotype will be a mixture of the two alleles.
