Dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus. The first allele is dominant and the second allele is recessive. For genes on an autosome, the alleles and their associated traits are autosomal dominant or autosomal recessive. Dominance is a key concept in Mendelian inheritance and classical genetics. Often the dominant allele codes for a functional protein whereas the
No Oceans are surrounded by North America however the Atlantic and Pacific Oceans surround North America. Also, the Hudson Bay is partially surrounded by North America. It is â¦ a Bay, however, not an ocean. Y'all missed one. The Gulf of Mexico also surrounds NA.
The Arctic Ocean touches North America, Asia and Europe. The ocean lies in the Northern Hemisphere and sits predominately north of the Arctic Circle. The Arctic Ocean includes a number of tributaries, including the Greenland Sea, East Siberian Sea, Barents Bay, Hudson Bay and Baffin Bay. The ocean connects to the Pacific and Atlantic Oceans. The ocean's size is 5,427,000 square miles, which is roughly the size of Russia and 1.5 times the size of the United States. The Arctic Ocean's coastline is approximately 28,200 miles long. The ocean consistently harbors large quantities of sea ice and is extremely difficult to navigate by boat during the winter months.
