Punnet squares are your friend with these kinds of questions :)

   <u>   A  |  a  |</u>
A <u>| AA | Aa |</u>
a <u>| Aa | aa |</u>

Now we can easily see that 1/4 of the offspring will be AA, 1/2 will be Aa, and 1/4 will be aa. Therefore, it is the third answer that's correct (1/4 AA, 1/2 Aa, 1/4 aa). Hope this helps! :)

What is one way that fish interact with a coral reef?
Ksivusya [100]

Fishes use the coral reef for shelter during the day as well as food.

<h3>Information related to coral reef</h3>

One way that fish interact with a coral reef is that fish hide within the coral. Coral reefs are an important resource for large-bodied fish in the Caribbean. They use the reef for shelter during the day.

Coral reefs are important ecosystems because coral reefs contain a great diversity of life. The color of coral depends on the type of polyp present. Coral polyps are tiny little animals that can live individually, or in large colonies that comprise a coral reef.

Great Barrier Reef is considered as the largest coral reef on Earth. Coastal land development, silt runoff, water pollution by humans, damage from scuba diving, boating, and fishing are the threats to the health of coral reef.
