1. an example of selective breeding is crossing a poodle and a labor-doodle that have desired traits. usually this is practiced on by plants and animals.
Various methods for selective breeding exist, from high-tech and costly processes such as in-vitro fertilisation or genetic engineering to more simple low-cost techniques that rely on the selection and controlled mating of animals based on observable characteristics.arious methods for selective breeding exist, from high-tech and costly processes such as in-vitro fertilisation or genetic engineering to more simple low-cost techniques that rely on the selection and controlled mating of animals based on observable characteristics.
