SS and ss. Since 100% of the offspring are spotted, then it would need to be SS so that it dominates over all. :)
Explanation:
Homologous chromosomes are 2 physically different chromosomes that have the same genes but are not genetically identical. Sister chromatids are 2 copies of a single chromosome and so are genetically identical (they also are physically attached to one another).
Plant cells do not perform respiration, so A,C, and D couldn't be correct but they don't digest either. so gain energy plants go through a light dependent reaction and the Calvin cycle which makes up photosynthesis.
2 would be A because fertilization is where the sperm cell and egg unite. 3 would be C because in the picture you can see how the division is occuring.
