This test requires the athlete to complete as many curl-ups as possible at a rate of 20/minute. This test provides a means to monitor the effect of training on the athlete's physical development.

It is expected the recessive allele becomes more prominent over time.
In general, nature favors traits that help organisms survive and reproduce. This occurs through a process known as natural selection that helps the population to evolve to have favorable traits.
This evolution occurs externally as organisms change their physical traits or phenotype, but also at a genetic level.
This implies that even if a trait is genetically dominant if the trait does not favor survival and reproduction, this trait will slowly disappear or reduce over generations.
Based on this, the recessive allele will become more prominent because this trait favors reproduction, while the dominant allele will become less prominent.
