Variations in evolution usually refers to variation of genes at a particular loci. This differs from diversity which is the total of genetic differences within a population. Speciation is the reproductive isolation of a subset of a population.
For the given situation above, I'm afraid I cannot answer your question since a pedigree chart isn't provided along with the question. You can resubmit your question together with the chart and we'll analyze it. Thank you for posting though. Here is what pedigree analysis is about.
Scientists have devised an approach, called pedigree analysis<span>, to study the inheritance of genes in humans. Pedigree analysis is also useful when studying any population when progeny data from several generations is limited. Pedigree analysis is also useful when studying species with a long generation time.</span>
