As far as I know, no.
mtDNA encodes some of the various components for the mitochondria such as the ETC (Electron Transport Chain) proteins such as ATP synthase and it's own ribosomal genes.
Here is a pretty good representation of what mtDNA looks like.

There are genetic diseases caused by defects carried on the mitochondrial chromosome that can have clear phenotypic consequences. http://www.umdf.org/site/c.8qKOJ0MvF7LUG/b.7934627/k.3711/What_is_Mitochondrial_Disease.htm

But a quick read suggests they don'y produce "traits" like the distinct phenotypes of Mendel's pea plants.

Read the sections on genocopies and phenocopies.

And who is the "we" here - all eukaryotes?
all organisms that are stuck with their inherited genetics, are exclusively sexual, have long generation times, place large investments in few offspring, and whose success depends on which chromosomes they recombine their chromosomes with (which mtDNA can't do)
