In Drosophila, the allele red eyes (b) is dominant to the allele for brown eyes (bw). At another gene locus on the same chromosome, the allele for thin wing veins (hv ) is dominant to the allele for heavy wing veins (hv). Flies homozygous for bw and hv are crossed to flies homozygous for bw and hv to obtain doubly heterozygous F1 progeny. What would be the results of a test cross with the F1 flies?

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.
