Assumptions: There likely are around 10,000 genes in the human genome. The population of the world is approximately 7,000,000,000 people. Assume each gene has only two alleles that do not mutate or change. How many possible genotypes are there

Assumed Human Genome

The number of possible genotypes are:

= 1,400,000 genotypes

Explanation:

Assumed number of genes in the human genome = 10,000

Approximate world population of people = 7,000,000,000

The number of alleles in each gene = 2 without mutation

A genotype = 2 alleles

The total number of genotypes based on these assumptions = 5,000 (10,000/2)

Possible number of genotypes in the human population = 1,400,000(7,000,000,000/5,000)

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.
