I do not know how the phylogeny chart you have is, but it probably contains a series of apes, gorillas and Homo sapiens.
We know that gorilas don't walk upright, but Homo sapiens do. What you will probably have to do is situate the new species of ape somewhere in between gorilas and humans, in a way that the new species shares a common evolutive path with both.
Hope it helped,

Answer:
1/16
Explanation:
To answer this question, you will need to set up a dihybrid cross since you have two traits that you are observing. Since the grey coat is dominant, we will label that with the genotype G and the recessive black coat will be g. Since the brown eye color is dominant, we will label that with the genotype B and the recessive blue eye color will be b. Both parent wolves will be heterozygous, which means their genotype is GgBb. Drawing the dihybrid square and filling in the spaces will allow you to have 1/16 are black coat and blue eyed puppies (ggbb). See the attached image for the cross.
Examples of chemical mutagens would be nicotine and other compounds in cigarette smoke that cause mutations involved in lung cancer.
