Answer:
Usually, cells will take between 5 and 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 and 20 hours.

Answer: This is called Monohybrid Experiment 
Explanation: Monohybrid Cross
P Generation	TT     *  	tt
  	Tall plants    	Dwarf plants
F1 Generation  
 T	T
t	Tt	Tt
t	Tt	Tt
In F1 generation;
There are 100% Tt Genotype and 100% Tall plant Phenotype
F2 Generation 
F1  	*  	F1
( Tt  	*  	Tt )
 T	t
T	TT	Tt
t	Tt	tt
In F2 Generation;
Genotype
There are 25% TT (homozygous dominant, tall plants).
50% Tt (heterozygous tall plants), and
25% tt (homozygous recessive dwarf plants).
This is how dwarf characteristics reappear in the second generation.
The Phenotype of F2 generation is 3:1  (Tall : Dwarf)
