Aa X Aa =

    A     a

A  AA  Aa

a   Aa  aa

Probability of producing an AA organism is 1/4

Design a laboratory-based experiment to test the hypothesis that algae need light to grow.
Shalnov [3]

The same algae is subjected to conditions in which one is exposed to light and another is not exposed to light while the nutrients in the both systems are kept the same.

<h3>What is algae growth?</h3>

The growth of algae is the process by which the organism increases in size. Now we know that that the algae is photosynthetic hence light must be required for its growth.

In order to verify this, the same algae is subjected to conditions in which one is exposed to light and another is not exposed to light while the nutrients in the both systems are kept the same.

The results of this experiment must confirm that the algae exposed to light grows better than the algae that was not exposed to light.
