If Mendel might have studied 7 pairs of characters in a plant with 12 chromosomes instead of 14 then:
1. | He could not discover an independent assortment |
2. | He might have discovered linkage |
3. | He might have discovered crossing over |
4. | He might have not observed dominance |

When AABBcc is crossed with AaBbCc then the ratio of hybrid for all three genes is:
1. 1/8
2. 1/4
3. 1/16
4. 1/32
