Answer:

2.Less than 73% of the populations would have only one allele present.

Explanation:

The two alleles chosen do not affect the fitness of flies in the lab environment, so Kerr and Wright could be confident that if changes in the frequency of normal and forked phenotypes occurred, they would not be due to natural selection.

Using a larger breeding population would not be expected to alter the outcome of the experiment.

jeyben [28]

<u>Answer</u>:- <em>Option 3 </em>(desert), <em>Option 4</em> (tundra) and <em>Option 5</em> (grassland).

<u>Explanation</u>:-

The amount of rainfall varies in different biomes:-

1. Tropical rain forests - The annual rainfall in these forests falls in the range of <em>125 to 660 cm</em> which varies according to the seasons.

2. Temperate rain forest - The annual rainfall in these forests can range from <em>200 cm to 350 cm</em> depending on the region where they are found. The annual rainfall is higher in warmer regions .

3. Desert - As the name suggests, the desert areas do not get enough rainfall. The annual rainfall in a desert is less than <em>25 cm</em>.

4. Tundra - It is a biome which is found in relatively cooler climates and the amount of rainfall is very less these regions. The annual rainfall in tundra biomes is less than <em>20 cm</em>.

5. Grassland - in these biomes, the rainfall is higher than the tundra and desert but is not as high as the rain forests and thus, grass is the dominant vegetation. The annual rainfall ranges from <em>60-90 cm</em>.
