The independent assortment of genes is a principle of Mendel and of genetics. Since humans are diploid organisms (they have 2 copies of their genetic information), we have that each gamete carries one of the two available alleles for each feature. These gametes are created in equal proportions.
We have that both parents are heterozygous for a feature, lets say H. Thus, their genotype is Hh. Hence, the child will get with probability 50%=1/2 H from the father and 50%=1/2 h from the father; same from the mother. By doing a Punnett square, we get that there is 1/4 chance that the child is HH, 1/2 chance that it is Hh and 1/4 that is hh. Since the disease is recessive (so both alleles are needed), we have that the chance that the kid has the disease is 1/4.
Explanation:
The atmosphere is the gaseous envelope round the earth.
The biosphere is the part of the earth dominated and occupied by living organisms.
As with other spheres of the earth, the biosphere and atmosphere are constantly interacting too.
- Organisms breathe in air to their respiration processes.
- Weather elements are conditioned by the atmosphere.
- Decomposition of organisms release gases back into the atmosphere.

That would be false. The Ozone layer is what protects Earth from UV radiation. The Ozone is part of the Stratosphere.
