In the first segment that covers the top part of the ocean the whale sharks producers serve as the basis of the food chain. In the top layer of the ocean enough sunlight hits the water which makes it a good place for planktons to grow. These planktons are then eaten by the whale sharks.
Phenotype = Observable/Physical characteristics.
Simple because there would be a larger gene pool, more opportunity for variation than a small population which has less of a gene pool and therefore less opportunity for variation.
Bacteria are prokaryotic organism that reproduce asexually. Bacterial reproduction most commonly occurs by a kind of cell division called binary fission.
Explanation:
When analyzing two linked genes there are 2 possibilities: either there is recombination between them during meiosis or there is no recombination. Crossing over happens during meiosis I, when each chromosome has two sister chromatids.
If no recombination happens, the 4 resulting gametes will be parental.
If recombination happens, 2 gametes will be parental and 2 gametes will be recombinant. For that reason, the maximum recombination frequency between two genes that can be calculated is 50% (recombination frequency = recombinants/total).
