What do the variables in the Hardy-Weinberg equation represent? p
p2
q
q2
2pq

p represents the frequency of the dominant allele (in decimal form) of a gene

q represents the frequency of the recessive allele (in decimal form) of a gene

These 2 alleles are different; one is dominant, one is recessive.

p^2 = the frequency of homozygous dominant individuals in the population (decimal form)

2pq = the frequency of heterozygous individuals in the population (decimal form)

q^2 = the frequency of homozygous recessive in the population (decimal form)

1 > q^2

2> 2pq

3 > q

4> p

5 > p^2

For some reason I can't add the answer names it's deemed as inappropriate sorry.

your answer is "the 1950's"

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.
