Answer:
Photoperiodism
Explanation:
The process explained in the question is called "Photoperiodism" which refers to the plants' reaction to the length of the dark and light period in a day.
When the dark period is interrupted with a certain period of artificial lighting, the plant thinks that the day had a longer period where it's "light" than it is "dark" so it gets tricked into flowering. Same concept can be applied in reverse for the plants who flower during longer periods of dark.

Explanation:
Answer:
In the F1 generation
RR = 0%
Rr = 50% (or 0.5)
rr = 50% (or 0.5)
Explanation:
A pink flowering plant has the genotype Rr. It is heterozygous for the allele. The alleles for this gene appears to show incomplete dominance, as the heterozygous phenotype is a blend of the two homozygous genotypes.
A white flowering plant has the genotype rr. It is homozyogous for the white allele
A punnet square of the cross is shown.
The resulting punnet square shows that only Rr and rr genotypes are possible, at a ratio of 50:50 (or 1:1). Therefore, the genotype frequency of Rr is 50%, and rr is 50% in the F1 generation. This can also be written as 0.5. It is not possible to get a red plant, as the genotype RR can not come from this cross
