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