The correct answer is no replacement behavior.
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.

The main cause of the seasons is this. The Northern Hemisphere has warm weather when the Earth is tilted toward the sun, and cool weather when the Earth is tilted away from the sun. Thus, option A is correct.
<h3>
What is Earth seasonal cycle?</h3>
The Earth's axis is currently inclined 23.5 degrees. The Earth rotates on its axis at a fixed tilt as it orbits the Sun. The Northern and Southern Hemispheres are tilted away from the Sun.
At different times of the year as a result of this angle. A hemisphere experiences winter and longer nights as it is tilted away from the Sun.
Therefore, there would be no seasonal cycle If Earth was not tilted.
