They are considered to be unique ecosystems in semi-sheltered areas near the ocean coastline. These areas often serve as nursing grounds where young marine life is protected during development.
<span>Fruit flies and pea plants may seem boring and simple, but the basic principles of genetics were worked out using those organisms. Humans follow the same patterns of heredity. First, meiosis independently assorts chromosomes when gametes are made for sexual reproduction. Second, human heredity involves the same relationships between alleles—dominant and recessive interactions, polygenic traits, and sex-linked genes, among others.</span>
