How the chromosome number is maintained in offspring?
are bivalent & tetrad the same thing?
Difference between chromosomes and chromatin?
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?
You have studied

What is DNA replication?
which structure of animal cell forms the asters of spindle?
cell division includes karyokinesis and cytokinesis. at what phase does the cytokinesis process BEGIN.?is it at the end of telophase, starting of telophase, end of prophase or starting of prophase?
Describe the following:
(a) synapsis (b) bivalent (c) chiasmata
Draw a diagram to illustrate your answer.

If meiosis II products have 10 chromosomes and 20 picogram DNA, then what will be the number of chromosomes and DNA amount respectively in G2 phase of meiocyte?
(1) 20 and 40 Pg DNA (2) 40 and 80 Pg DNA
(3) 20 and 20 Pg DNA (4) 20 and 80 Pg DNA
And the answer is given (4). I cant understand the explanation given also:--
Answer (4) In normal meiocyte,, chromosome = 2n
DNA = 2C
G1 = 2n, 2C
S = 2n, 4C
G2 = 2n, 4C
After meiosis II,,n, 1C in each haploid cell

Draw a diagram to illustrate your answer.
Chromosomal material condenses to form compact mitotic chromosomes. Chromosomes are seen to be composed of *chattached* together at the centromere.
Also, define the term *chattached*.
