Crossing over at prophase I results in the linked genes (those on the same chromosome) becoming unlinked and separated. Prophase I is this first stage of meiosis, the chromosomes condense, form tetrads, and exchange DNA. The nucleolus and nuclear envelope disappear.

We know that arteries from the aorta and arteries from coronary arteries supply oxygenated blood to various parts of the body. What separates these two is the coronary arteries’ ability to deliver oxygenated blood to the heart.
We know that the inferior vena cava delivers deoxygenated blood to the lower (hence inferior) part of the body and that the superior vena cava delivers deoxygenated blood to the upper (superior) part of the body; they follow the same deoxygenated rule and strictly deliver nutrients to certain parts of the body.

The answer to this is inherited mutation.
Inherited mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people.
Hope this helped :)
Have a great day
Answer:
A all of the genes found within the ecosystem
Explanation:
Genetic diversity is the amount of variation in the genetic make up of individuals in a population. Genetic diversity is important for the fitness of a population, increased genetic variability allows populations to adapt to changes in the environment or resources. It is also important for continually producing healthy offspring, reducing the chance that recessive, deleterious alleles will be expressed.
