Which of the following is unique to mitosis and not a part of meiosis?
a)	Homologous chromosomes behave independently
b)	Chromatids are separated during anaphase
c)	Homologous chromosomes pair and form bivalents
d)	Homologous chromosomes crossover

(a)

During mitosis, all the chromosomes behave independently while during meiosis, homologous chromosomes pair up through synapsis and form bivalents in zygotene substage of prophase-I, then in pachytene substage, crossing over occurs between homologous chromosomes and during diplotene substage of prophase-I of meiosis chiasma formation takes place.

During anaphase of both mitosis and meiosis, chromatids are separated and pulled towards opposite poles.
