If chromosome complement 44+XY of a gamete mother cell suffers a non-disjunction at the of first meiotic division. Which sets of gametes will be correct

Which of the following cell undergoes first meiotic division during spermatogenesis?

Differentitae between spermatogensis and oogenesis on the basis of: Nature of meiotic divison undergone by gamete mother cells.

In Pinus male gametes are produced in the pollen tube by the division of which of the following cells

Dyad stage of formed, in which type of cytokinesis during meiotic division of microspore mother cell?

In which phase of cell division the chromosomes are set free in the cytoplasm?

Statement (s) Nondisjunction is the failure of paired chromosomes to segreagate during the metaphase of meiotic division of fametogenesis Reason (R ) Non disjunction results in production of abnormal gametes

Assertion: In haploid organism, specialised cells called meiocytes (gamete mother cells) undergo reduction division. Reason: Chromosome number in the meiocyte is half the number of chromosome in gamete.
