Explanation:
The size of crystals in igneous rocks can tell us about the physical environment under which the rock formed.
Igneous rocks are rocks that are derived from molten magma formed within the crust.
- When large crystals are formed, it suggests that the magma has cooled slowly without any disturbance. Slow cooling of magma makes minerals to surround nucleation centers easily an take their time to form.
- When small crystals are formed, we can infer that cooling was rapid. Magma had to cool rapidly and several nucleation centers resulted.
- Large crystals in rocks are usually produced deep beneath the earth crust forming a rock type known as plutonic igneous rocks.
- Those with small crystals that forms on the surface are called extrusive or volcanic igneous rocks.

The cell divides and grows in the organ of origin, causing a localized tumor. Cancer cells then spread to adjacent tissues or regional lymph node drainage areas, and then advance to distant organs or structures, creating metastatic tumors.
ABO blood group determination is a example of multiple Alleles.
<h3>What is Multiple Alleles?</h3>
Multiple alleles refer to a type of non-Mendelian inheritance pattern that comprises of more than the normal two typical alleles that is dorminant and recessive alleles that usually code for a certain characteristic in a species.
Examples of multiple Alleles is the genes of ABO blood group determination.
Therefore, ABO blood group determination is a example of multiple Alleles.
