another cross with the offspring of the first cross. List genotypic and
phenotypic ratios for each cross.

The genotypic ratio from the crossing of a red-flowered snapdragon with a white flowered and advancing it to F2 one would be 1 R1R1 : 2 R1R2 : 1 R2R2 and the phenotypic ratio would be 1 red : 2 pink : 1 white

Monohybrid crossing

The red flower snapdragon is homzygous for the R1 allele while the white flower one is homzygous for the R2 allele. The R1 allele has incomplete dominance over the R2 allele.

Crossing R1R1 individual with a R2R2 individual:

                  R1R1    x    R2R2

               R1R2   R1R2   R1R2   R1R2

All the F1 progenies are R1R2 (pink)

Crossing two F1 progenies:

                R1R2    x    R1R2

             R1R1   R1R2   R1R2   R2R2

Genotypic ratio: 1 R1R1 : 2 R1R2 : 1 R2R2

Phenotypic ratio: 1 red : 2 pink : 1 white
