Since the two species co-inhabit the same habitat, habitat isolation can be disregarded as a factor keeping the two species separate. There are however some other broad categories of mechanisms for <span>reproductive isolation. One is behaviour. Many birds in particular have very specific mating rituals, including mating dances, particular bird song, the development of specific mating plumage, the release of specific pheromones and the building of a particular nest structure. Another broad category is mechanical isolation. You will find that the genital organs of particular species are very specific, and preclude other close species from successfully mating. Another broad category is gametic isolation. For most species combinations, it is not possible for the gametes to fuse successfully to form a hybrid. If hybrid games do fuse, in many cases, the hybrids are sterile, such as mules for example. </span>
Answer:Quantitative Genetics
Explanation:Quantitative Genetics deals with genetics that shows continuous vary characters. Quantitative Genetics shows the continuous distribution on segregating generation.
Explanation:
The similarity between tropic and nastic movement is - both are the result of external stimulus and the difference between tropic and nastic movement is the direction of the response is not dependent on the direction of the stimulus in the case of nastic movement but in the case of tropic movement, the response is dependent on the moment.
The gas produced by respiration ,which is carbon dioxide, is the they type of gad that plants need to survive. The principles plants need to survive is carbon dioxide, water, and the sun's solar energy. And the things the give off is oxygen and natural sugar. While we need oxygen to be able to breath the need our carbon dioxide to survive as well, so it works in a cycle.
