The very common questions on SRFP In an angiosperm, male diploid, female tetraploid. Ploidy of endosperm? Ploidy of seed?
On Human Reproduction As in a beautiful one: A 36 year old female has 2 children, if menses start at a age of 12 years, then calculate the number of secondary oocyte and ova on till age....
The approach and the idea: 36 current age, started at 12 years, so (24X12) ova should have released. But, 2 kids, so 2X9 gestation period, no ova released, plus, 6X2 months lactation period. So here we go, no. of ova till that age is 288-30 i.e. 258
In general, be crystal clear on MEIOSIS Always remember, MEIOSIS 1 gives HAPLOID Melosis 2 happens to separate sister chromatids.
