Bivalent first appears in
diplotene
pachytene
zygotene
leptotene
In how many cells the meiotic division has taken place, if the total number of spermatids produced are 32?
4
16
8
32
In which phase of meiosis homologous chromosomes separates?
Anaphse I
Anaphase II
Metaphase I
Metaphase II
Synaptonemal complex has a role in
Chromosome pairing
Chromosome movement
Chromosome segregation
Chromosome organisation
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
During which stage of prophase I the crossing over takes place?
Exchange of paternal and maternal chromosome material during cell division is called
dyad formation
crossing over
synapsis
bivalent formation
Meiosis is reductional division where as, meiosis II is equational division due to
Pairing of homologous chromosomes
Disjunction of homologous chromosomes
Separation of chromatids
Crossing over
The number of chromosomes becomes half in
anaphase I
anaphase II
telophase I
telophase II
Chiasmata show the sites of
spindle formation
maternal chromosomes
