During what stage of meiosis 1 does the exchange of genetic information occur?

This is due to two phenomena in Meiosis 1: 1) Independent assortment: In metaphase 1 each daughter cell randomly receives either a maternal homolog or paternal homolog from each chromosome pair. 2) Crossing over in Prophase 1 creates the exchange of genetic material between homologous chromosomes, during synapsis.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
