Yeah it is possible. So if I am remembering college correctly a chimera in biology is when two zygotes merge in the first few days of life. This means that some of the cells will divide off zygote one and some off zygote two. This can lead to stark lines in phenotype expression. Such as two colored animals.
Though also if I remember correctly the color in cars is sex linked. So if the cat is female. One X chromosome could have one color and the other X chromosome could have a different color. Depending on which X is activated in each cell it can lead multiple colors. That is how you get calico cats. I just can’t remember if that can lead to this type of color expression.
Oh and just because someone is going to wonder white is not a color. It is the lack of a color.
If you check the level of both the door and the slab it will let you know which one is causing the gap. I would guess that a gasket would be the best fix. If it is the door DO NOT try to fix it yourself. Those springs can very easily kill you. I have known life long contractors that will do everything in a house but a garage door. Garage doors are not DIY.
Look I know everyone is saying don’t but I think you can do it pretty easily. So I have seen masons do brick and stone facades in the middle of winter. They had concrete blankets and diesel heaters. It worked just fine. I would get two tarps and a blanket and build a little tent with tarp, blanket, tarp. Then put a little electric heater in there. Newer electric heaters are much safer than the old ones with the ones exposed resistance elements. Just think you don’t have to get it really hot. Not like it is going to catch fire until a few hundred degrees as long as the heater is not touching the tarp there is no real chance of that happening. Plus if it is just barely freezing at night then it really just needs to really work for a few hours.
Well I can’t tell you the exact gene would need to be changed, there are plenty of animals able to deal with the salinity of sea water. Basically the kidney has a certain ability to concentrate salt. The greater the ability the saltier the animal’s urine is and the saltier water can be consumed.
If I am remembering correctly the threshold for salinity of water that can be consumed is up to a level just below that of the threshold of the kidney’s ability to concentrate salt.
So we would not need “super kidneys” just normal ones similar to those of one of many animals in the sea. But we might have a shortened kidney lifespan because of it.
First off does the switch even have power to it? The switch should be breaking the hot wire (hopefully). So one side of the switch should be hot. A non-contact voltage tester will tell you this very quickly and easily. They aren’t that expensive and a wonderful tool to have. Great for helping test and Trace or double checking the breaker is off before you lick the wires.
