Wild cabbage has evolved into new varieties fike cabbage, broccoli and cauliflower bya)genetic driftb)natural selectionc)reproductiveisolationd)artificial selectionCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

Correct answer is Option (d) Artificial selection. Because, it does not occurs naturally. It is man made for to lead his life easily.

Artificial selection is the process of selecting desired (more wanted) trait, when breed (to cross) with other plants/animals to get desired (more wanted) traits.

Examples:- Obtaining of Dogs from Wolves, Obtaining of Kohlrabi Cauliflower, Broccoli, Cabbage, Red cabbage, Kale from Wild cabbage.

Option a, b, and c occurs naturally by leaving the option d as it is a man made process.

Hence, Option d is correct friend...

Answer

Artificial selection is the process in which specific features of an organism are selected . Artifical selection involves the cultivation of new crops with disirable from one single parent .

Answer

Introduction:
Wild cabbage is a plant species that has undergone evolution to give rise to new varieties like cabbage, broccoli, and cauliflower. Evolution is the process by which species change over time, and it occurs through various mechanisms such as genetic drift, natural selection, reproductive isolation, and artificial selection. In the case of wild cabbage, the most relevant mechanism that has led to the development of new varieties is artificial selection.

Explanation:
Artificial selection is the process by which humans intentionally select and breed individuals with desirable traits to perpetuate those traits in future generations. This practice has been utilized by humans for thousands of years to modify and improve various plant and animal species to suit their needs.

How artificial selection applies to wild cabbage:
Wild cabbage, also known as Brassica oleracea, is the ancestor of cabbage, broccoli, and cauliflower. Through artificial selection, humans have selectively bred wild cabbage plants with specific traits to develop new varieties.

Selection for specific traits:
Initially, humans would have identified wild cabbage plants with desirable traits such as larger leaves, thicker stems, and a milder taste. These plants were then selectively bred, allowing the desired traits to be passed on to future generations.

Repeating the breeding process:
This process of selecting and breeding plants with desirable traits was repeated over generations, gradually leading to the development of distinct varieties like cabbage, broccoli, and cauliflower. Each variety was bred to enhance specific traits, resulting in plants with different appearances and flavors.

Human influence:
The key factor in artificial selection is human influence. Humans determined which traits were desirable and actively intervened in the breeding process to ensure that those traits were preserved and amplified. This is different from natural selection, where the environment determines which traits are advantageous for survival and reproduction.

Conclusion:
In conclusion, wild cabbage has evolved into new varieties like cabbage, broccoli, and cauliflower primarily through artificial selection. Humans selectively bred plants with desirable traits over generations, resulting in the development of distinct varieties with specific characteristics. This process highlights the significant impact that human intervention can have on the evolution of species.
