He sequenced the gene controlling leaf color, he found that:
Plants with green leaves have the genotype GG.
Plants with yellow leaves are heterozygous, with the genotype Gg.
He then crosses two plants with yellow leaves and observes that:
one-third of the offspring are green and
two-thirds of the offspring are yellow.
Which of the following explains this observation?
The G and g alleles are codominant
The G and g alleles show incomplete dominance
The g allele is a homozygous lethal
The G allele has incomplete penetrance
