Detailed explanation-1: -The farmers saved kernels from plants with desirable characteristics and planted them for the next season’s harvest. This process is known as selective breeding or artificial selection. Maize cobs became larger over time, with more rows of kernels, eventually taking on the form of modern maize.
Detailed explanation-2: -This process is immoral as it induces fear and anxiety in whatever animals are being subjected to a new environment. On top of this, artificial selection can have detrimental effects on these animals, such as obesity, diseases, health disorders, and can even lead to smaller brain size.
Detailed explanation-3: -Artificial selection or selective breeding describes the human selection of breeding pairs to produce favorable offspring. This applies to all organisms – from virus to four-footer, and from pet to food source. Artificial selection aims to increase the productive or esthetic value of an organism to our advantage.
Detailed explanation-4: -Choose a species. Choose a trait of interest. Breed them together. Identify which individual shows the desired trait strongly. Breed that trait for the next generation. Repeat 4 & 5 steps for many generations. 06-Feb-2022
