Dihybrid Cross
Give me the phenotypic ratio of the following Dihybrid cross.
Tall-dominant
Dwarf-recessive
Purple Flowers-dominant
White-recessive
Cross a plant that is heterozygous for both traits with a plant that is homozygous tall with white flowers.

Ok Ashley, nice try but remember this is a dihybrid cross. You must take into account all the possible phenotypes. Look for them in this order: Dominant-dominant(tall and purple):daminant-recessive(tall & white):recessive-dominant(Dwarf & purple):recessive-recessive (dwarf & white)
The result should add up to 16 because their are 16 boxes in a dihybrid punnet square.
ex. 4:4:4:4 Together these add up to 16.
Nice Job Andrew!!! That is exactly right!
