Question

Hybridization _____.

Answer 1

Answer:

usually produces offspring that cannot reproduce

Explanation:

Hybridization is the process of crossing two organisms usually of different species, genus or families but of desirable characters to produce organisms known as hybrids.

Hybrid organisms combine the characteristics of both parents and because of the difference in genetic composition of the parents, they are often sterile and hence, cannot reproduce.

Therefore, hybridization usually produces offspring that cannot reproduce.

Answer 2

Answer:

The correct answer is: c) usually produces offspring that cannot reproduce.

Explanation:

Hybridization, also knowns as selective breeding, is an artificial process that involves selecting parents with specific characteristics in order to obtain an offspring with the same traits.

Hybridization is very common and has been performed by humans for thousands of years: from selective breeding crop plants, to do so with dogs in order to create more desirable breeds.

Option A is incorrect because hybridation does not occur in nature, it is an artificial process.

Option B is incorrect because hybridation often happens when the selected parents are chosen to reproduce (by a human).

Option D is correct because an important amount of hybrids are sterile (for example: mules).

Option D is incorrect as well because the offspring is not identical: it shares a combination of genes from both parents.
