Unformatted text preview: A X A , X A X a , X a X a , X A Y, or X a Y or X A X ? (2) What inheritance pattern do you think is shown? ? (Autosomal Recessive, Autosomal Dominant, X-linked Recessive) Could be EITHER recessive pattern – but more likely X-linked Recessive since it is primarily in males. Can you rule out the other two patterns? Are you 100% certain, or are you doing it by probability. Explain. Autosomal Dominant can be ruled out because two individuals who do not express the trait (gen II, individual #1 & 2) can’t have an offspring with the trait if it was autosomal dominant. It is VERY BENEFICAL to go through the entire pedigree and determine the genotype of each individual. If you can’t determine one of the alleles, just use a ?. AA, Aa, aa or A? or if X-linked: X A X A , X A X a , X a X a , X A Y, or X a Y or X A X ?...
