Finish the Punnett square below. Which genotype is recessive? what are 3 indicators that chemical change has occurred? list 3

The block D has the recessive genotype.

The recessive genotype of a particular character is the genotype having both the recessive allele of that particular character. The recessive genotype expresses the recessive character which isn't seen in any other genetic combination. So recessive individuals are important ro determine.

Here only the last square has the individual with genotype bb which is the recessive genetic character of that organism. So the recessive characteristics is expressed by this organism only.

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.
