Allopatric speciation, also referred to as geographic speciation, is a method of the formation of new species due to isolation of the species from one another through geographic means.
The first step in this process is geographic isolation, which means that the original population is divided into two groups due to geographical reasons such as movement of continents or formation of water bodies.
Next, the species are subjected to different selection pressures due to their different environments. Eventually, the gene pool becomes very different for the two species due to the different selection pressures and because they are not allowed to mix.
Finally, after enough time passes, speciation occurs, which means that the two populations cannot breed to form fertile offspring.
A monhybrid cross is the inheritance of a single character and dihybrid cross is the inheritance of two difference character.

Urine contains the harmful toxins which need to be eliminated from the body. Darker urine is more concentrated. It is indicative of the fact that unnecessary toxins and wastes are circulating in your body which could mess with your health. This, again, depends on how much fluids you drink throughout the day. But there could be many other reasons responsible for the same.
.Oxygen free environments
.Concentrated salt water and hot
. Acidic water of sulfur springs
