Answer:
For recessive traits to be observed, dominant genes must be absent.
Explanation:
There are 3 possibilities for the genes: AA, Aa, aa.
in both AA and Aa, there is a dominant gene present. If a dominant gene is present, it will always show the dominant trait.
In aa, there is no dominant gene present, and there are only recessive genes. Because of this, the recessive trait is observed!
Taxonomy s the branch of science that deals with the classification of living and extinct organisms.
Using taxonomy, plants and animals are classified according to the following: Domain, Kingdom, Phylum, Class, Order, Family, Genus and Species. Taxonomy is also used to identify the species that are related to each other.
Organisms are named using the binomial system of nomenclature that was developed by Linnaeus. The binomial system, also known as the scientific name, is consist of two parts: the Genus name and the Specific Epithet.
For this problem set, the Mergus serrator and the Mergus merganser is closely related to each other, since they both have the same Genus.
Due to global warming, the climatic conditions such as rise in temperature of the coral habitat in the oceans changes. The corals become stressed by changes in conditions. Under these conditions, corals expel the symbiotic algae living in their tissues. This turns corals completely white. This is called coral bleaching. Due to coral bleaching, it becomes more stressed and this can leads to its death. Algae also may not be able to survive alone.
