Why did the F1 offspring of Mendel's classic pea cross always look like one of the two parental varieties?     No genes interacted to produce the parental phenotype.     Each allele affected phenotypic expression.     One allele was dominant.     The traits blended together during fertilization.

Mitochondrial Mutations

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
