Mendel drew from his monohybrid cross was that the two alleles  in each plant separate when gamete are formed, and one allele goes into each gamete.

The two alleles of an individual plant separate with equal probability into the gametes.

The DNA-binding domain occupies residues 1–59. It contains two a-helices separated by a turn. This is a common DNA-binding motif known as the HTH (helix-turn-helix); the two a-helices fit into the major groove of DNA
