Nothing flashy, but a quick review of inheritance followed by a silent tutorial on how to use/read a pedigree. Remember a few vocabulary that we discussed:
Autosomal chromosome– this is referring to your body chromosomes
Sex chromosome – this is referring to your sex chromosomes (X & Y for humans)
Dominant – this is referring to an allele for a trait that can mask a recessive trait (typically shows in every generation)
Recessive – this is referring to an allele for a trait that is masked by a dominant trait (typically skips a generation)
