Crossing over is the main event in meiosis and heredity as it leads to genetic variation.
<h3>What is genetic variation?</h3>
Genetic variation is the changes that take place in the genes of individuals that can lead to the formation of new characters.
it generally occurs in meiosis specifically during crossing over.
Thus, it can be concluded that crossing over between non-sister chromatids during meiosis is significant in heredity as it leads to genetic variation.

Answer:
young
Explanation:
Most crust in the ocean basins is less than 200 million years old, which is much younger than the 4.54 billion year age of the Earth. This fact reflects the process of lithosphere recycling into the Earth's mantle during subduction.

Answer:
Non-Mendelian inheritance
Multiple alleles, incomplete dominance, and codominance
Explanation:
In the real world, genes often come in many versions (alleles). Alleles aren't always fully dominant or recessive to one another, but may instead display codominance or incomplete dominance.
