Answer:
The correct answer will be-located on chromosomes.
Explanation:
GregorJohann Mendel is known for his experiments on pea-plants or Pisum sativum which led to the evolution of theory of genetics. He is also known as the "father of genetics".
He studied seven traits of garden peas that were plant height, seed shape, seed coat tint, unripe pod color, pod shape, flower inflorescence and flower color.
His experiments became successful because the genes (Factors) of each character are located on the seven sets of chromosomes (2n=14) as:
Trait Chromosome number
1. seed color - 1
2.seed shape and flower- 1
3.mature pod- 4
4.plant height - 4
5. inflorescence- 4
6. unripe pod- 5
7.mature seeds- 7
These pair of alleles were transmitted to offsprings in crosses and became successful.
Thus, located on chromosomes is the correct answer.
