1. Were any of your physical traits autapomorphic or synapomorphic when plotted on the gene trees? Which ones and for which species? Phylogeneticists often refer to these physical traits as "evolutionarily significant," what do you suppose they mean by this?

The right answer is B) It is homozygous for fur color.

Homozygosity consists in an individual carrying for the same gene two similar variants (alleles), which is the case for all individuals with phenotypic characters derived from recessive genes. For example, when one has blue eyes, one is obligatorily homozygous for the gene coding the color of the eyes since the blue allele is recessive.
