Answer:
Because the F1 plants all had a lowercase a/short plant allele, there was a 25% chance that two plants would contribute it to their offspring and they both did sometimes to make a aa offpsring.
Explanation:
All the F1 plants were heterozygous, so when they were crossed, the resulting genotypic ratio was 1 AA : 2 Aa : 1 aa. As you can see, this is the first time since the parent generation that there is a aa genotype and short plant phenotype, so that's why short plants reappeared.

Answer:
Due to less number of chlorophyll.
Explanation:
The variegated leaves accumulates or produces less amount of food than non-variegated leaves under similar condition because variegated leaves has number of chlorophyll as compared to non-variegated leaves. Chlorophyll is a green pigment that is responsible for the photosynthesis in plants, without chlorophyll no photosynthesis occurs in the plants. The variegated leaves has less number of chlorophyll as compared to non-variegated leaves which leads to less production of food in variegated leaves.
