Explanation:

For Dogs: Artificial selection in dogs is done to develop traits like specific sizes (e.g., toy breeds for companionship, working breeds for tasks like herding or guarding), temperaments (friendly for pets, protective for guard dogs), or physical abilities (speed for racing, strength for pulling). Breeders aim to get dogs with desired characteristics for roles such as companionship, work (police, herding), or show.

For Cows: Cows are artificially selected to increase milk production (dairy cows) or improve meat quality and quantity (beef cows). Also, traits like disease resistance, growth rate, and docility are selected to enhance productivity in farming, whether for milk, meat, or labor (though less common now for labor).

For Fruits (e.g., bananas): Artificial selection in fruits like bananas is to improve traits such as size, sweetness, shelf - life, resistance to pests and diseases, and ease of cultivation. Breeders want fruits that are more appealing to consumers (better taste, appearance) and easier to grow and transport for the agricultural industry.

Answer:

• Dogs: To develop desired traits for companionship, work (e.g., herding, guarding), or show, such as specific sizes, temperaments, or physical abilities.
• Cows: To increase milk production (dairy), improve meat quality/quantity (beef), and select for traits like disease resistance, growth rate, and docility.
• Fruits (e.g., bananas): To improve size, sweetness, shelf - life, pest/disease resistance, and cultivation ease for consumer appeal and agricultural productivity.
