What term describes the offspring of two genetically different plants?

1. Clones

2. Hybrids

3. Varieties

4. Strains

The correct answer is: Hybrids

The term that describes the offspring of two genetically different plants is hybrids. When two different parental plants are crossbred, their offspring exhibit a combination of traits from both parents, leading to genetic variation. This genetic mixing can enhance certain desirable traits such as yield, disease resistance, or adaptability, which is why hybrids are often created in agricultural practices for improved performance. Clones refer to organisms that are genetically identical to the parent plant produced asexually, which is not applicable in this context. Varieties refer to different cultivars within a species that have distinct characteristics but are not necessarily the result of crossing genetically different plants. Strains typically refer to genetically distinct lines within a variety, often used in reference to microorganisms or specific cultivars. In contrast, hybrids signify the specific genetic mixing that occurs when two different parent plants are combined.
