First: Set up the Parental Cross P 1 A = axial flowers Male a = terminal flowers Female AA X aa
SET UP THE PUNNETT SQUARE
Put the Alleles in Separate Boxes
A Monohybrid Cross
Now Perform an F1 Cross A = axial flowers Male a = terminal flowers Female F1 = First Offspring Aa X Aa
Put the Alleles in Separate Boxes
Perform the Cross
Assess The Genotype and Phenotypes GENOTYPES AA 1 Aa 2 aa 1 Ratio 1:2:1 PHENOTYPES Axial Flowers (AA, Aa) 3 Terminal Flowers (aa) 1 Ratio 3:1
Assess The Genotype and Phenotypes Axial Flowers 3 Terminal Flowers 1 Ratio 3:1 GENOTYPES AA 1 Aa 2 aa 1 Ratio 1:2:1
First: Set up the Parental Cross P 1 . F =flying f = walking P = purple p = orange FFPP X ffpp MALE FEMALE
PARENTAL P1 DIHYBRID CROSS
