<span>Crossover is the first way that genes are shuffled to give rise to genetic diversity. Crossover takes place in sexual reproduction. Chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other. When they break at the same place (locus) in the sequence of base pairs, the result is an exchange of genes called genetic recombination. That is the normal way for crossover to occur. Genetic recombination ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity is created.</span>
<span>Except for identical twins, all the other human beings are genetically distinct from each other is ture because of </span>sexual reproduction.

Answer:
- the region surrounding the earth or another astronomical body in which its magnetic field is the predominant effective magnetic field.
- the region of Earth’s magnetic field shaped by the solar wind
Explanation:
A magnetosphere is a region around any celestial body producing magnetic field. It is the portion of magnetic field around the Earth which interacts with the charged particles emitting from the sun at high speeds. It is a pear shaped magnetic field region surrounding the Earth. It is shaped by the solar wind.
Thus, the correct answer is b. the region of Earth’s magnetic field shaped by the solar wind
