The answer is; Mantle
Convection currents in the mantle drive tectonic plate movements. The convection currents in this regions are like those of water. The cooler upper mantles sink to the bottom and the hotter lower mantle rises. This circulation causes fiction drag with the overlying crust and therefore causes it to drift.
Answer:
a. The frequency of the g allele= 0.6
b. The frequency of the G allele= 0.4
c. The frequency of the GG genotype= 0.16 or 16%
The frequency of Gg genotype= 0.48 or 48%
Explanation:
According to the given information, the disorder is homozygous recessive trait. The frequency of the homozygous recessive genotype (gg) in the population (q^2)= 36% or 0.36
Therefore, the frequency of the recessive allele "g" (q) = square root of 0.36= 0.6
Since p+ q = 1
Therefore p= 1-q = 1-0.6= 0.4
The frequency of the dominant allele "G" (p)= 0.4
The frequency of the homozygous dominant genotype GG = p^2= 0.4 x 0.4 = 0.16 or 16%
The frequency of heterozygous dominant genotype Gg = 2pq = 2 x 0.6 x 0.4 = 0.48 = 48%
Pine trees grow the most in spring and summer. maple trees barely start growing in late summer or early fall.
