"A parakeet with green plumage is crossed to a white parakeet. The progeny are all green. Crossing these progeny together gave the following offspring: 3 white, 8 blue, 29 green, and 9 yellow. Propose a genetic hypothesis to explain the results. -g

This is due to the theory of independent assortment of gene.

This means that gene separate and assort with each other, independently. There a gene that is recessive in the parents may not be recessive in the offspring.

A recessive gene is the gene that makes up the physical appearance of the offspring. While a dominant gene is the gene that exist in the offspring, but is not among the gene that makes up the physical appearance of the offspring.

For the two pure stock parent plants, their have yellow and blue as the dominant gene, while green and white are the recessive gene.

That's is why the yellow and blue gene has a tendency of occurrence in future generations.

For their first progeny which appears to be all green, is because the green gene has sorted themselves independently to be recessive, while others become dominant.

For the second progeny, the recessive gene from the parent plants which was carried by the offspring as dominant gene, now became recessive in some plants.

answer; i believe its (ovulation);

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.
