Use a punnett square to explain how a dominant allele masks the presence of a recessive allele

In this example I used blue and brown eyes. Brown eyes are a dominant trait and are represented by a big B while blue eyes are recessive and represented by a little b. If an offspring gets a B from the father and a b from the mother the offspring will have brown eyes.

Hope this helps!!

When a virus infects a host cell, it uses the cell's machinery to make copies of its own genetic material in a process called replication. finally, during the process of self-assembly, that protein shell and the copies of the virus's genetic material are assembled into new viruses.

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.
