Question
Can someone kindly explain: 1. What is the ratio of phenotypes from a monohybrid 1a. What is the ratio of phenotypes from a dihybrid 1b. What is the ratio of geneotypes from a monohybrid 1b. What is the possible genotypes of the parental generation (P generation) that eventually give you the 9:3:3:1 dihybrid corn (which is the F2 generation)Can someone kindly explain: 1.

Explanation / Answer
1. In Mono Hybrid cross the F2 Phenotypic Ratio is 3 : 1 (3=Dominant i.e. 1 Homozygous Dominant and 2 Heterozygous Dominants; 1 = Recessive)
1a. What is the ratio of phenotypes from a dihybrid: 9: 3: 3: 1
9 = Parental Dominants; 1 = Parental Recessive; 3 & 3 Recombinant Characters due to Independant Assortment
1b. What is the ratio of geneotypes from a monohybrid : 1: 2: 1
1b. T =Tall; t = Dwarp where t<T; R = Round, r = Wrinkled, where r < R
The possible parent genotypes are: TTRR X ttrr or TTrr x ttRR or ttrr x TTRR or ttRR x TTrr
