Asked by amy

it is not known if a tall pea plant is homozygous or heterozygous (a hybrid). you decide to do a test cross to find out. if there are 40 offspring and 7 out of them are short, what is the genotype of the unknown pea plant? draw a punnett square that represents this cross.

please explain this to mee , thank you

From the F1 generation, I would assume that Tall is dominant and short is recessive. What genotypes would give you approximately 25% short.

Cannot draw a Punnett square here.
