If we take a look at the phylogenetic tree of bears presented in the picture above, we can see that the branch number one is the common ancestor to all living bear species, which means that the whole group has a uniform origin. and the
phylogenetic tree has a root. Therefore, the group is monophyletic, not <span>polyphyletic ( meaning that the whole group has the same origin) and not paraphyletic ( there is no group that has been excluded from the tree).</span>

Answer:
Different colour occur due to heterozygous nature.
Explanation:
Most of the puppies just like parents because the black colour gene or allele is dominant over other colour allele whereas other colour puppies also formed due to presence of heterozygous type of alleles. Other colour occurs due to appearance of recessive allele in the physique of the offspring or formation of hybrids occurs which causes colour other than black and white in the offspring.
