Biology: The Genetics of Blood Types

This week we continued learning about genetics. Once again we carried out a simulation. However, there were a couple key differences from last week:

  • Last week "parents" produced 1 child with a lot of different traits, and this week "parents" produced MANY kids, focusing only on a single trait.
  • Last week the kids looked at made up traits, such as star- vs blast-shaped eyes, while this week they looked at a true example: ABO blood types.
  • Because we had such a large sample size of offspring, we were able to compare the distribution of the different genotypes and phenotypes to what we would predict based on chance alone.
