Question

A gardener grows petunias (the flowers shown above) in a variety of colors, mostly in various shades of pink and purple. If she wanted to grow a

generation of only dark purple petunias, how could she use selective breeding to achieve her goal? Which color flowers would she breed together and
why?

Answer 1

Step-by-step explanation:

To achieve her goal of growing a generation of only dark purple petunias, the gardener could use selective breeding to crossbreed two petunias that have the desired traits. In this case, she would breed two petunias that have the darkest shade of purple that she wants to achieve. By doing this, the offspring will have a greater chance of inheriting the desired traits, and the gardener can continue this selective breeding process over several generations to produce a stable and predictable variety of dark purple petunias.

The reason for breeding the two darkest purple petunias together is to increase the likelihood that their offspring will inherit the genes responsible for producing the dark purple pigment. By selectively breeding for this trait over multiple generations, the gardener can create a population of petunias with the desired color and other desirable traits.
