According to the research, Earth's mantle is hotter than the crust.
<h3>What is the Earth's mantle?</h3>
It is the solid layer that lies between the central core of planet Earth and the earth's crust.

If the frequency of one allele in a population is 0.7, then the frequency of the alternate allele is 0.3.
Allele frequency is determined by dividing the number of times the allele of concern is seen in a population by the total number of copies of all the alleles at that specific genetic locus in the population.
In case all the allele occurs at the same frequencies in sperm cell and eggs cell, and gametes bond together accidentally to produce zygotes, then the Possibility that any two alleles will combine to form a particular genotype equals the product of the allele frequencies.
