When the rocks are removed from a desert's ecosystem, the animals that depend on those rocks for homes would be in trouble. If these animals died due to predators and a lack of homes, then the other animals (predators) that depend on them for food would start to need other sources of food. This would cut into another predator's food supply and so on.
Answer:
1/2 or 50%
Explanation:
Let us assume that the existence of heterozygous dark male means that the dark trait is dominant over the light trait. Hence, the light color trait is recessive.
Let us also assume that the dark color trait is represented by the allele A and the light color trait by allele a.
Heterozygous dark male = Aa
Light female = aa
Crossing the two:
Aa x aa
Aa Aa aa aa
Aa = dark color = 1/2 or 50%
aa = light color = 1/2 or 50%
<em>Hence, the probability of producing light-colored moths would be </em><em>1/2 </em><em>or </em><em>50%.</em>
