experiments followed from mendals cross and developed from the conclusions he made as a result of the first monohybrid cross. State what ratio of offspring he would have predicted from these crosses. b Calculate the actual ratios obtained in each of these crosses. c Suggest what chance events may influence the actual ratios of offspring obtained in breeding experiments like these. (We will return to this issue at a later point. For example, the statistical test known as the chi-squared test can be applied to the results of genetic crosses to test whether the actual results are close enough to the predicted results to be significant.)

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.
