A cross ia made in tomatoes between a female plant from a pure line that is trisomic for chromosome 6 and a normal diploid male plant that is homozygous for the recessive allele for potato leaf (pp).

a) A trisomic F1 plant (PPp) is back crossed to potato leaved male. What is the ratio of normal leaved plants to potato leaved plants when you assumed that p is on chromosome 6?
b) What is the ratio of normal- to - potato leaved plants when you assume that p is not located on chromosome 6?
c) What is the ratio of normal to potato leaved plants when PPp is selfed?
