A. The waves would be exactly the same at points A and B.
Explanation:
The seismic waves at both point A and B would be exactly the same at the two points.
Seismic waves are elastic waves that spreads out concentrically in all directions from their source.
- Both S and P waves are body waves that moves within the earth.
- In a seismic station, the p-waves or primary waves arrives first before the s-waves or secondary waves.
- At any point equidistant from the epicenter, baring any geologic differences in the subsurface, the waves would be exactly the same at all points.

Answer: a. Genetic recombination (crossing over)
b. Can also be explained in terms of crossing over
c. Non disjunction of homologous chromosomes in meiosis 1
Explanation:
The process that allows for the transfer of both the paternal and maternal materials to is the crossing over process that takes at meiosis 1 changing them to secondary spermatocytes. While they are still primary spermatocytes, they are still diploid cells having both the maternal and paternal chromosomes. But since the spermatozoon is an haploid cell, it is able to retail some of both parents chromosome by the crossing over event which takes place between homologous paternal and maternal chromosomes allowing them to exchange materials. Thus the chromosomal contents of the primary spermatocyte differs from that of the spermatozoon.
C. This can occur as a result of the one of the homologous chromosome pair refusing to separate at meiosis 1 with one gamete containing 4 chromosomes/8 sister chromatids and the second having 2 chromosomes/4 sister chromatids.
