are bivalent & tetrad the same thing?
Difference between chromosomes and chromatin?
You have studied
plants dont have centrioles, so how are the spindle fibres formed for cell division? how can it divide without centriole? n if it can , why do animals need the centriole? What is its main function? arent spindle fibres formed by centriole? if nt then wer r they formed?
what is anastral mitosis?

q2 what is genetic recombination?
q3 what is genetic mapping?
q4 what is diffrance between mitosis and meiosis?
q5 what is cell cycle and what's the function of cell cycle? please answer me as soon as it 's possible
