Question

artificial selection

1. what is selective breeding?
2. who picks the traits that get passed on during the selective breeding process?
3. complete the chart:

selective breeding
advantages
disadvantages

Explanation:

1. Selective breeding is a process where humans intentionally breed plants or animals with desirable traits to produce offspring with those traits.
2. Humans pick the traits that get passed on during the selective breeding process.

3.

• Advantages:
• Can produce organisms with desired characteristics (e.g., higher crop yield, better milk production in cows).
• Can eliminate some negative traits over generations.
• Can create new varieties of plants and animals.
• Disadvantages:
• Reduces genetic diversity (makes populations more vulnerable to diseases and environmental changes).
• Can lead to the spread of recessive, harmful traits if not carefully managed.
• Long - term effects on the health and viability of the species may be unknown.
