You identify a gene that controls fin size in zebrafish and after examining many fish you realize that in the population only two alleles exist for this gene. One allele is wild type leading to normal fins, and the other allele leads to small fins. Interestingly, only homozygous dominant individuals have a normal fin size, and all other individuals have small fins. What is the most likely explanation for the single-gene interaction of the fin alleles

The Correct Answer is  "Haploinsufficient"

Explanation:

Haploinsufficiency is a component of activity to clarify a phenotype when a diploid living being has lost one duplicate of a quality and is left with a solitary practical duplicate of that quality. Haploinsufficiency is regularly brought about by lost capacity transformation, in which having just one duplicate of the wild-type allele isn't adequate to deliver the wild-type phenotype.  

It happens when a living being has a solitary utilitarian duplicate of a quality, and that solitary duplicate doesn't create enough item to show the wild sort's phenotypic attributes. The general supposition that will be that the single staying useful duplicate of the quality can't give adequate quality item (regularly a protein) to protect the wild-type phenotype prompting a modified or even infected state.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .

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.
