The true statement is that it evidences the dramatic negative results every time when the poles of the magnet get reversed.
Option D
<u>EXPLANATION: </u>
There are two poles: North and South Pole in Earth's magnetic field. When lava erupts at mid-ocean ridge, it cools and becomes a hard rock. During this process of cooling, the rock becomes magnetised.
Scientists have discovered that the magnetic field of Earth has been reversed in direction hundreds of times, which means that the polarity of North pole and South pole reverses.
Due to this reversal, a pattern of magnetic stripes is created in symmetry on both sides of the mid-ocean ridges.
Despite the fact that the female lays the eggs and the young develop outside her body, since the sperm and the egg combine inside the female, internal fertilization takes place.

Answer:
A. They have different genetic sequences but are found in the same location on a chromosome.
Explanation:
In genetics, alleles are the variant form of a gene. According to Mendel, there are usually two alleles for most genes except for few cases where there are multiple alleles. Each allele of a pair is contributed by each parent during sexual reproduction. For example, in a gene Tt, the alleles are T for tallness and t for shortness.
Alleles of the same gene are related in such a way that they have different genetic sequences but are found in the same location on a chromosome. The different genetic sequences makes them alternative form of each other.
