Answer:

The correct answer is option C. "pleiotropy".

Explanation:

Pleiotropy is a characteristic that defines a gene that is responsible for the development of multiple traits, which often seem to be unrelated. Sickle-cell disease is an example of a disease caused by the mutation of a pleiotropic gene, resulting in the person developing red levels, blood clots, and strokes. Other example is the disease phenylketonuria, at which the affected person suffers from a mental disorder and reduced hair and skin pigmentation by a single mutation in a single gene on chromosome 12.

Explain how the processes of sea-floor spreading and magnetic reversal produce bands of oceanic crust that have different magnet
WARRIOR [948]

Explanation:

As the two plates move away from each other in a divergent boundary, the magma from the mantle beneath rises to replace the void created. The magma then cools into a new crust. Before the magma cools, the iron minerals align themselves with the magnetic fields of the earth due to their ferromagnetic properties. These cause the rocks after they are cooled to seem to have bands.

Due to magnetic reversals of the earth's magnetic fields (i.e change in magnetic north and south poles) over several hundred thousand years, these bands will orient differently depending on the then earth magnetic polarity when the magma was cooling.

Long eyelashes is the dominant trait because, in the last sentence, donna mentioned how nearly everyone in the family had long eyelashes, while barbara and her had short ones. this proves that long eyelashes are much more common in the family than short eyelashes, which means long eyelashes would be dominant, while short eyelashes would be recessive.
