Lets say that the genotypes are:
Male affected:XbY
Male unaffected: XaY
Female affected: XbXb
Female carrier: XaXb
Female unaffected:XaXa
P: XbY x XaXa
F1: XaXb XaXb XaY XaY The middle square is female carrier.
P:XbY x XaXb
F1: XaXb XbXb XaY XbY The left square is affected female.
P:XaY x XbXb
F1: XaXb XaXb XbY XbY The right square is affected male.
Answer: A) Ocean water evaporates and the warm, moist air rises higher into the atmosphere.
Explanation:
The Equator receives the most direct sunlight on Earth. This makes the water near the Equator, and air above the water, typically warmer than surrounding areas. This warm, moist, less-dense air rises, and then cools as it travels through denser, colder layers. This constant cycle of evaporation and condensation creates an abundance of rain.
So, oceans near the Equator provide ideal conditions for rainfall because ocean water evaporates and the warm, moist air rises higher into the atmosphere.
