Some plants fail to produce chlorophyll,and this trait appears to be recessive.Many plants also self-pollinate.If we locate a pea plant that is heterozygous for this trait,self-pollinate it and harvest seeds,what are the likely phenotypes of these seeds when they germinate?
A) All will be green with chlorophyll since that is the dominant trait.
B) All will be white and lack chlorophyll since this is self-pollinated.
C) About 1/2 will be green and one-half white since that is the distribution of the genes in the parents.
D) About 1/4 will be white and three-fourths green since it is similar to a monohybrid cross.
E) About 1/4 will be green and three-fourths white since it is similar to a monohybrid cross.

Where g = no chlorophyll and G = chlorophyll, a heterozygote would have the genotype Gg. If the plant self pollinates then the genotype for ova production is Gg and the genotype for pollen production would be Gg. This monohybrid cross would yield the 1:2:1 ratio (25%, 50%, 25%) typical of such a cross.Bloom's
