What are chiasmata? What is their significance?

How many chromatids are involved in crossing over at one chiasma?

Synapsis, chiasma formation and crossing Over occur between homologous chromosomes in ………………………… of meiosis.

Interference is 1. decrease in frequency of crossing over because of heterochromatin 2. chiasma at one point disfavours formation of chiasma at second point 3. both correct 4. none of the above

The given diagram of a cell undergoing meiosis, indicated that crossing over occurs only at the chiasma Which of the following gametes will NOT be formed from this cell
