Selective breeding refers to the
A.
mating of two organisms that have survived an environmental change by having mutations.
B.
process where organisms select a mate based on who has the most advantageous traits.
C.
deliberate mating of two organisms with the intention of producing offspring with desirable traits.
D.
process where organisms from different species mate to produce offspring that form a new species.
C. deliberate mating of two organisms with the intention of producing offspring with desirable traits.
The table shows what bananas looked like before and after humans started to selectively breed them.
Which best describes why the bananas vary so greatly in appearance?
A.
The bananas vary in appearance because humans bred them for the most undesirable traits.
B.
The bananas vary in appearance because humans bred them for the most desirable traits.
C.
The bananas vary in appearance because humans started eating different types of bananas.
D.
The bananas vary in appearance because humans stopped eating bananas altogether.
C.
deliberate mating of two organisms with the intention of producing offspring with desirable traits.
The correct answer is C. Selective breeding refers to the deliberate mating of two organisms with the intention of producing offspring with desirable traits.
To arrive at this answer, you can first eliminate options A, B, and D as they do not accurately explain selective breeding.
- Option A states that selective breeding involves mating organisms that have survived an environmental change by having mutations. However, selective breeding is not necessarily related to environmental changes or mutations.
- Option B suggests that organisms select a mate based on advantageous traits. While advantageous traits can play a role in selective breeding, it doesn't account for the deliberate human intervention in the breeding process.
- Option D mentions the process where organisms from different species mate to produce offspring forming a new species. This process is known as hybridization or crossbreeding, not selective breeding.
Therefore, option C is the correct answer, as it accurately describes selective breeding as the intentional mating of organisms to produce offspring with desirable traits.
