Group of answer choices

1:0

0:1

1:2

1:1

Answer 1

If all of the poisonous frog's eggs are genetically engineered right after fertilization to include a gene that prevents poison production, then all of the offspring would be non-poisonous. Therefore, the ratio of poisonous to non-poisonous frogs in the offspring would be:

**0:1**

This means there are no poisonous frogs and all frogs are non-poisonous.
