i) What is synaptonemal complex?
ii) Explain the significance of crossing over with diagram. In which phase of cell division this process takes place?
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
