Answer:
See the answer below
Step-by-step explanation:
1. Tt x Tt
TT Tt Tt tt
Assuming that T is dominant over t:
Genotype ratio = 1TT:2Tt:1tt
Phenotype ratio = 3:1
2. Rr x Rr
RR Rr Rr rr
Assuming that R is dominant over r:
Genotype ratio = 1RR:2Rr:1rr
Phenotype ratio = 3:1
3. Assuming that green (G) is dominant over the other color (g). Heterozygous green would be Gg
Gg x Gg
GG Gg Gg gg
Genotype ratio = 1GG:2Gg:1gg
Phenotype ratio = 3:1 (green ratio the other color)
4. Assuming that green (G) is dominant over the other color (g) as above:
homzygous green plant = GG; heterozygous green plant - Gg
GG x Gg
GG Gg GG Gg
Genotype ratio = 1GG:1Gg
Phenotype ratio = 100% green
5. Assuming that tall (T) is dominant over short (t)
Homzygous tall plant = TT
short plant = tt
TT x tt
Tt Tt Tt Tt
Genotype ratio = 100% Tt
Phenotype ratio = 100% tall
