Less

I do not know.

All members (sister chromatids) in a tetrad are involved in a single crossover event.

True

False

I do not know.

What is the maximum % of recombinants that can be observed for a single crossover event?

100

I do not know.

What would be the recombinant gamete/s from this parent?
