Pedigree Analysis

Basic Pedigree Analysis

Students infer dominance and linkage of rare diseases from pedigrees.

 

 

 

Basic Pedigree Analysis with Explanations

Students infer dominance and linkage of rare diseases from pedigrees. Students post their reasoning, by (1) identifying family patterns, (2) identifying dominance and/or linkage hypotheses (3) that must be true or cannot be true, (4) and explain why.

 

 

Pedigree Analysis and Carrier Probabilities

Students infer dominance and linkage of rare disease from pedigrees, calculate the probability that unaffected individuals are carriers and calculate the probability that an unobserved individual is affected.

 

 

Pedigree Analysis and Carrier Probabilities with Explanations

Same as Pedigree Analysis and Offspring Probability, but students also explain reasoning behind each probability calculation.
