To accomplish this, gametes carrying genes fuse to create zygotes which then grow and differentiate. b. d. vary in appearance due to adaptations to different environments. Let's review some important concepts and terms. c. allopatric. One species performs a specific courtship dance. $$ For example, in India both the lion and tiger exist and are capable of interbreeding; however, the lion lives in the grasslands and the tiger lives in the forest. Biologists who concur with the lineage species concept reject the importance of reproductive isolation to speciation and the evolutionary process.

The various species concepts are mutually exclusive. The fertilized egg is called a zygote and has the potential to grow and differentiate into an adult form of the species. According to the biological species concept, members of the same species look alike primarily because they Create your account. It includes a phase in which some individuals are reproductively incompatible with other individuals in the same population. Reproduction can be prevented from pre-zygotic barriers, which prevent a zygote from forming or they can be post-zygotic barriers where a zygote can be formed but it can not successfully mate as an adult. In cases of gametic isolation, however, the animals do come into contact, but the gametes (reproductive cells) are not compatible. In 1783 , Jacques Charles launched his first balloon filled with hydrogen gas, which he chose because it was lighter than air. Two species of sage from California provide an example: The two-lipped flowers of Salvia mellifera have stamens and style (respectively, the male structure that produces the pollen and the female structure that bears the pollen-receptive surface, the stigma) in the upper lip, whereas S. apiana has long stamens and style and a specialized floral . a.
