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.

THE PHENOTYPE OF THE DIHYBRID IS 0TT:2Tt:2tt
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.
Would it be something like this-
8:8:0:0
8 tall purple
8 tall white
0 dwarf purple
0 dwarf white
Nice Job Andrew!!! That is exactly right!
Hello Coach Fullington I dont know what you are talking about. So will you please break it down to me and explain it more to me because you know iam very special?
8 tall purple
8 tall white
0 short purple
0 short white
