anaphase-II
prophase-I
interphase
both prophase-I and II
As compared to mitosis in meiosis
Two replication cycle of DNA is followed by two divisions
Four diploid cells are formed
Every chromosome behaves independently
Genetic variabilities are introduced in daughter cells
Meiosis II is a _________.

Similar to Meiosis I
Equational division
Both (a) and (c)
Bivalent first appears in
diplotene
pachytene
zygotene
leptotene
