Overproduction results in more individuals in a population than the resources can support. What does this cause?

Explanation:

Overproduction result in when populations produce more progeny which has the ability to live and survive all through the reproductive age. Overproduction lead to competition.

Competition occur as a result of too much population on a limited resources. Because the population is more than the resources, organisms tend to compete for food, nesting , space, nest which affect their ability to reproduce successfully and also survive.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
