large reptiles with muscular tails, large teeth, and strong jaws. Like nearly all reptiles,
alligators hatch from eggs.

the results of an experiment conducted with alligator eggs. Scientists incubated the eggs of one
alligator species at different temperatures. When the eggs hatched, the scientists counted the
numbers of males and females born in each group of eggs.

A dog breeder has begun to raise Labrador retrievers. So far, she
hasn't been able to predict the color of the puppies that she breeds. She does not know that dark fur
(D) is dominant over yellow fur (d).
When the
breeder crossed a yellow female Labrador retriever with a male Labrador with dark fur, she expected
half of the puppies to be yellow and half of the puppies to be dark. However, in a litter of 8
puppies, all had dark fur. The breeder next crossed the same yellow female with a different dark
male. This time, half of the puppies were yellow and half were dark. | |
