<span>Answer: the genes for the two traits assort independently.
The proportion </span><span>9:3:3:1 is found when studying two genes at the same time,</span><span> known as a dihybrid cross.
Mendel did this cross and found that the offspring, had 4 different phenotypes, but in different quantities . </span>This ratio led Mendel to develop the law of independent assortment.
The rocks near the mid-ocean ridge were younger then rock near trenches. Matching bands of magnetic rocks were found on either side of the mid-ocean ridge; bands like tree ring - record changes in earths magnetic field over time. Earthquake data showed oceanic crust is sinking on to the mantle at trenches.
