Answer:

A) The two genes are unlinked and are assorting independently, leading to a 1:1:1:1 ratio of phenotypes in the offspring.

Explanation:

The χ2 value means nothing on its own--it is used to find the probability that, assuming the hypothesis is true, the observed data set could have resulted from random fluctuations. A low probability suggests the observed data is not consistent with the hypothesis, and thus the hypothesis should be rejected. The hypothesis that you are testing are two genes are unlinked and are assorting independently, leading to a 1:1:1:1 ratio of phenotypes in the offspring.

What is the orientation of the magnetic stripes of iron contained in rocks that support the idea of seafloor spreading?
Feliz [49]

The answer is; north and south

When magma rises in the divergent boundary, as new crust is formed, the iron minerals in the magma align themselves with the earth’s magnetic field before the magma cools to rock. Iron minerals have a ferromagnetic property about them. This is why the rocks layers in the sea floor spreading have bands. As the earth’s magnetic field flips regularly, the iron elements also change alignment in tandem.
