Mendel referred to what we know of as alleles as ""factors."" What did he conclude happens to these factors during gamete formation? A. the factors separate B. the factors combine C. the factors merge

option A. the factors separate

Explanation:

The Mendel referred alleles as factors. Mendel was unaware about gene but he knew that there are two factors for a single character. The single factor gets transferred from each parent. The gene contains two alleles/factors. The alleles/factors from both mother and father separates at the time of formation of gametes. These gametes from both parents containing alleles/factors recombines and thus forming a zygote.

Thus, factors separate during gamete formation. So, option A is correct.
