Solution

The correct option is C Four chromosomes
When Mendel studied characters together, he was very fortunate for all the seven characters chosen were controlled by seven pairs of alleles located on four chromosomes and luckily they were located on seven different pairs of homologous chromosomes. He did not know about this fact. If any two different pairs of alleles were to present on the same pair of chromosomes his conclusion would have been different.
