For her science fair project, your little sister replicated one of Mendel’s experiments. From a P0 pea plant with purple flowers and a pea plant with white flowers, she got 1 purple F1 hybrid (she had forgotten to water, so just one survived). From this self-fertilized F1 she got 8 F2 offspring. 7 were purple and 1 was white, for a 7:1 ratio. Did your little sister just disprove Mendel’s laws?
A. Yes. This, and other examples of non-Mendelian genetics demonstrate that Mendel’s Laws are actually incorrect and misleading.
B. No. When another pea pod forms on the plant, that will bring the numbers up to the correct 9:3, or 3:1 ratio
C. No. Dehydrating the parent caused Lamarckian selection on the offspring.
D. No. Random chance can cause deviations in the ratio of small numbers of progeny.

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.
