Answer:

Law of Dominance: This regulation sates that during a couple of contrasting developments the allele this is expressed is dominant while the allele that isn't expressed is recessive. Long stem dominant over Short stems.

Explanation:

(Parental gen)    TT                              X                     tt

(Homozygous lengthy stem plant)                          (Homozygous quick stem plant)

(F1 era)                                  Tt

(Self pollination)                         Tt       X      Tt

(F2 era)                         TT        Tt          Tt           tt

Here:

TT: Homozygous dominant lengthy stem plant

Tt: Heterozygous dominant lengthy stem plant

tt:   Homozygous recessive quick stem plant

(a) In 2d era, 75 %  of rose flowers may have lengthy stem flowers.

(b) Following the punnet checker board, the phenotypic ratio of F2 era plant is 3:1 and the genotypic ratio is 1:2:1.

(c) Law of Dominance: This regulation sates that during a couple of contrasting developments the allele this is expressed is dominant while the allele that isn't expressed is recessive. Long stem dominant over Short stems.
