Jorge is conducting an comparative experiment where he is comparing the heights of adults who grew up taking a certain
vitamin and adults who did not. He finds that those who took vitamins are, on average, 2 cm taller. What is a major limitation of
his experiment?
Large amounts of information can be gathered.
It is repeatable.
He can not show definitively that vitamins cause a person to be taller.
No relationship can be shown between vitamins and height.

Use this new information to determine the parents’ genotypes (indicated by red arrows). then calculate the probabilities that the second male offspring will have each condition. drag one pink label to each pink target and one blue label to each blue target. then use the white labels to answer questions 1 and 2. labels can be used once, more than once, or not at all.

Depending on the organism the number of in a cell may change
