The selective breeding helps to maintain pure breed and hence exclude the hybrids.
<h3><u>Explanation:</u></h3>
Selective breeding is a very commonly practiced procedure in plant management and animal husbandry. This selective breeding helps to achieve and maintain the homozygous traits of selective characters. For example, if two dogs with white colour are breed, then their progenies will be white too. Thus the selective character i.e fur color will be maintained.
In crops, if the plants with desired fruit characteristics are bred with each other then superior quality of fruits are achieved and maintained over generations. This is very essential economically too.
Earth's tilt on its axis affects the way heat is distributed on Earth's surface.

More tilt means more severe seasons, that is warmer summers and colder winters where as less tilt means less severe seasons, that is cooler summers and milder winters.
