The decreased oxygen levels in the water will affect the respiration of the fishes. In order to cope up with the change, the fishes may migrate to a better place with higher levels of dissolved oxygen. This however does not relate to the process of natural selection as the fishes are still the same, genetically and phenotypically. Natural selection acts on those fishes that are able to survive the decreased oxygen levels. These fishes will breed and increase their numbers. The new generation of fishes will be tolerant to the lower oxygen levels. This new phenotype indicates a change in the genetic composition of the fishes.
Answer:
When the dominant allele does not cover up the recessive.
Explanation:
The mix and is considered incomplete.
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.
The end result is production of four haploid cells (n chromosomes, 23 in humans) from the two<span> haploid cells (with n chromosomes, each consisting of </span>two<span> sister chromatids) produced in </span>meiosis<span> I. The four main </span>steps of Meiosis II<span> are: Prophase </span>II<span>, Metaphase </span>II<span>, Anaphase </span>II<span>, and Telophase </span>II<span>.</span>
