Many human traits are complex, because more than one gene controls them. As a result, there are a variety of possible traits. For example, there are several possible eye or hair colors among humans. Even with this complexity and variance, there are traits that tend to show a dominant or a recessive inheritance pattern. This table shows some common dominant and recessive traits in humans and gives the genetic abbreviation for each trait.

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
