Genotype
The FIRST time you draw this pedigree, you will assume the trait is autosomal dominant. Use the alleles "A" and "a" to figure out what everyone's genotype is.
The SECOND time you draw this pedigree, you will assume the trait is autosomal recessive. Using a new, clean drawing, and starting from scratch, write in the alleles "A" and "a" for the trait being inherited in an autosomal recessive patter.
The THIRD time you draw this pedigree, you will assume the trait is X-linked Dominant. Use the chromosomes X^A and X^a and Y (remember, males are XY and females are XX) to show everyone's genotype and sex chromosomes.
The FOURTH time you draw this pedigree, you will assume the trait is X-linked Recessive. Use the chromosomes X^A and X^a and Y to show everyone's genotype and sex chromosomes.
