Ice calving is the breaking off of chunks of ice at the edge of a glacier as a result of erosion
These variations are most likely the result of polygenic effects. Polygenic traits are controlled by many genes.
<h3>Polygenes and inheritance</h3>
The phenotype is any observable feature of an organism, which depends on genotype and environment.
The inherited genes largely determine different phenotypic features (e.g., eye color, weight, etc).
Traits controlled by a single gene are called monogenic, whereas traits controlled by two or more genes are known as polygenic.
