=-=-=-= 20 Points! =-=-=-= Fill in the Punnett square below, which represents the crossing of two heterozygous dominant people who have hairy hands, but carry the allele for hairless hands. People carrying a recessive allele without displaying the trait are called carriers.

Combining the alleles H and H gives you HH on top left

Combining the alleles H and h gives you Hh on top right

Combining the alleles h and H gives you Hh on bottom left

Combining the alleles h and h gives you hh on bottom right

Genotype ratio HH:Hh:hh=1:2:1

Phenotype ratio hairy:hairless=3:1

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
