The eroded material finds its way to the bottom of oceans because of gravity (from... According to the hypsometric curve (plot between elevation and % of earth's surface), only about 29% of Earth's surface is above the mean sea level, rest 71% has an elevation less than mean sea level.
Hope this helped and I hope I answered in time!

Answer:
The man's father genetics for aniridia is XAY because one copy of the altered gene in each cell is sufficient to cause this disorder.
Explanation:
The aniridia allele in females has to be in the XAXA or XAXa form to be expressed but in males, can be expressed when genotype is XAY.
Migraine headaches allele in females has to be in the XMXM or XMXm form to be expressed but in males, can be expressed when genotype is XMY.
A man with normal vision and without migraines (XaY/XmY) had a father who had aniridia (XAY).
The man's father genetics for aniridia is XAY because one copy of the altered gene in each cell is sufficient to cause this disorder.
