Question 1

Normal fruit flies have brownish-yellow bodies, and this body color is dominant. A mutation in the gene for body color can produce files with an ebony body color. A homozygous normal fruit fly (e+e+) is crossed with a homozygous ebony fruit fly (ee). What is the predicted outcome of this genetic cross?

All the offspring will have ebony bodies

Of the offspring, 75% will have brownish-yellow bodies, and 25% will have ebony bodies.

All of the offspring will have brownish-yellow bodies

Of the offspring, 75% will have ebony bodies, and 25% will have brownish-yellow bodies

Question 2

Genetic drift of Howea forsteriana

Natural selection of adaptive traits in both species

Gene flow between the two species

Mutations in Howea belmoreana

Question 3

New species of frogs that feed on both the fungus and the infected species of frogs will evolve

Plants will no longer grow in the waters of the affected ecosystms, and fish species will increase.

The fungus will move on land and destroy reptile and mammal populations in tropical ecosystems.

Populations of algae and mosquitoes will increase, leading to fish die-offs and potential increases in human malaria cases.
