In horses, the genes for white coat color and red coat color are codominant. heterozygotes have a light red coloration, called roan. if you located a population of wild mustangs in a valley that had 476 red horses, 323 roan horses, and 51 white horses, could you say the population is in hardy weinberg equilibrium? first calculate p and q, then use the hardy-weinberg formula to calculate expected genotypic frequencies.

P is allele for red

Q is allele for white

PP is homozygous genotype for red and its frequency is p 2

QQ is homozygous genotype for white and its frequency is q2

PQ is hetrozygous genotype for roan with the frequency 2pq.

If the poppulation is in HW equlibrium than p2+2pq+q2=p+q=1

p= 476/467+323+51=0.56 p2=0.3136

q=51/467+323+51=0.06 q2=0.0036

pq=323/467+323+51=0.38 2pq=0.0672

0.56+0.06+0.38=1

The population is in Hardy-Weinberg equilibrium.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
