These genetics problems have my mind in a mush. Any help at all would be appreciated.Farmer Morris has a green tobacco plant. He doesn't know the genotype of this plant. He crosses this unknown plant with a plant that is homozygous recessive for chlorophyll and gets the following results: two green plants for every two white plants. (Phenotypic ratio = 2 green: 2 white)So, what is the genotypic ratio of the offspring? This kind of cross would be called?The "hint" I was given said "Hint: draw a Punnett square and cross the known plant with all possible green plants." Maybe the hint will help...it didn't help me.
