Answer:
We know that the sample is 35% adenine, which tells us that it is also 35% thymine. We know that cytosine and guanine pair together and will be present in equal amounts, so we can divide this final total by 2 to find our answer. The sample is 35% adenine, 35% thymine, 15% guanine, and 15% cytosine.

Different phenotypes must exist in equal proportions is NOT one of the conditions that must be met for evolution by natural selection to take place. It depends on the genetic variation in the population.
<h3>Selection, evolution and genetic variation</h3>
Genetic variation is a prerequisite for evolution (and consequently natural selection) to occur.
Genetic variation represents the primary matter for which phenotypes are differentially adapted to the environmental conditions in which individuals live.
This process (natural selection) leads to the differential reproduction and survival of the fittest phenotypes.

Primary sources are original materials/information on which other research is based. It includes journal articles of original research, conference papers, dissertations, technical reports, and patents. Primary sources are also sets of data, such as health statistics, which have been tabulated, but not interpreted.
