Last summer you were walking in the woods when you stumbled upon a group of four tiny baby squirrels. You noticed that they all had different tail lengths. Curious, you decided to measure the tail lengths of the four squirrels. Their tail lengths were found to be: 30 mm, 38 mm, 32 mm, and 28 mm. The heritability for tails in squirrels is 0.33. (This is a fraction, not percent.) What is the variance due to the difference in environment (VF)? Round to two decimals and do not include units.

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.
