Purple flowers are dominant over white flowers. the parent generation includes two heterozygous parents.  what are the possible phenotypes of these parents’ offspring?   3 purple and 1 white 3 white and 1 purple 1 purple, 2 lilac, and 1 white 1 white, 2 speckled, 1 purple

3 purple and 1 white

Explanation:

As it is mentioned in the question purple flower is dominant over white flower then purple P and white r, so heterozygous parents will be Pr as shown in the figure.

Now by the Law of Dominance, which states that dominant trait will be appear in next generation so phenotype of these offspring will be 3 purple and 1 white flower.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
