Family Pedigree With Traits
Purpose: To examine inheritance by tracing family traits
Procedures: Using the family genealogy chart that you created in the Family Pedigree assignment, add traits for each member of your family. You MUST choose at least 5 traits, but you may choose up to 10 for extra credit.
Remember the following rules:
Note: In order to keep the task manageable, you may need to limit your focus to one side of your family. Clearly indicate and label the subject of the genealogy chart (themselves or another adult).
Marking family traits:
Every family as a set of traits that is peculiar to their family, such as large noses. From the table below, find at least five traits, but no more than ten, to trace on your family pedigree. Clearly indicate and label the traits that you are tracing. Use the letter below to indicate a particular allele, and upper case letters for the dominant allele, and lower case letters for the recessive allele. For example, for tongue roller, use the letter "T" for family member who can roll their tongue, and "t" for family members who cannot roll their tongue. As much as possible, use different letters.
Table of Traits:
Note: Use the subscript N for nose size, E for ear size, and Y for eye size, and L for eyelash length.
It’s always useful to also include some of the following information, if you have it.
Finally, write an analysis detailing the process of creating the chart. You should discuss successes and problems encountered in creating the chart as well as any surprises or discoveries made during the process. A paragraph or more should be devoted to analyzing the genetic traits of the relatives on the chart. What patterns related to genetics and inheritance do you see in your chart? Finally, what hypotheses or conclusions can you draw from examining your genealogical data?
