Answer:
Principles by Mendel
Explanation:
The heritage principles of Gregor Mendel are at the core of modern genetic engineering. Mendel has created three heritage principles by conducting experiments with pea plant breeding, which described the passing on of genetic characteristics before anyone thought that genes did exist.Mendel referred to this components as "elementen" and suggested that, throughout sexual reproduction, each parent contributes a form of elementary elementen to the resultant offspring. This blend of parental elementen then defined what type of characteristic was noticeable in the descendants.
Genetic concepts are laws or guidelines regulating the biological heredity process, the transition of parents' to children's attributes by information that is biochemically transmitted by DNA, to gene units.
Answer:
Adaptations to a common environment and examples of convergent evolution
Explanation:
Convergent evolution is a process by which two independent and phylogenetically separated organisms, get to develop similar structures or behavior to survive. These structures make possible a better performance in a similar environment. These organisms are morphologically or ethologically similar in their whole bodies or just in parts.
Convergent evolution occurs in different phylogenetic branches independently from each other. It results from the need of different organisms to adapt to a similar environment and to solve a problem from that particular ecological niche. Ecological pressures acting on them might be similar, modeling the organisms´ phenotype. Each evolutive branch ends by developing the same structures, which they both find effective in their environment.
In the exposed example, Ichthyosaurs (reptile) and fishes are separated species on evolutive time, corresponding to different phylogenetic lineages. Both of them inhabit the same aquatic environment. Pressures of the habitat acted on them and modeling their phenotypes. These species need to adapt to living in water, moving, feeding, scaping, chasing, etc. So both species arrived at the same solution. They developed dorsal fins and tails, which are important to stabilize the body in the water while swimming, making it more hydrodynamic and getting to propel better.
