The likely answer to that question is FALSE; mitochondrial chromosomes are NOT responsible for inherited traits such as: eye color, height, intelligence.
Mitochondrial DNA is responsible for making enzymes involved in oxidative phosphorylation and to provide instructions for making molecules such as transfer RNAs (tRNAs) and ribosomal RNAs (rRNAs), which are chemical cousins of DNA (RNA that plays an integral role in the assembling of amino acids into functioning proteins for the mitochondria.
