red fruit (R) is dominant over yellow (r) and tallness (T) is dominant over short (t) in tomato plants. what phenotype and genotype ratio would result if one of parent is red homozygous and tall homozygous and other is tall heterozygous and red heterozygous

The gamete formed by RRTT will be of one type only, which is RT. And gamete formed by RrTt will be RT, Rt, rT, rt.
Gamete RT Rt rT rt
RT RTRT RRTt RrTT RrTt
RT RRTT RRTt RrTT RrTt
RT RRTT RRTt RrTT RrTt
RT RRTT RRTt RrTT RrTt

Phenotype of all offsprings is red and tall. And the genotypic ratio is 1:1:1:1

so the genes of the parntz r...RRTT RrTt..n the offspring r full red tall plant 100% bt the genotype is inthe ratio..RRTT;RRTt;RrTT;RrTt
