Facts (generated by robot; please edit if you find it inaccurate)

• A typical pedigree of an autosomal dominant trait is shown in Fig.
• An autosomal dominant trait is a gene that is not related to the chromosome that determines gender; therefore, it affects boys and girls equally.
• A phenotypically normal woman in a family where an autosomal dominant trait is segregating and her mother and son are affected.
• An autosomal dominant trait is one in which the inheritance of a dominant gene on an autosome, not a sex chromosome, causes the characteristic to be expressed.
• b) Is it possible that the pedigree above is for an autosomal dominant trait? c) Write the genotypes next to the symbol for each person in the pedigree below assuming that it is for a dominant trait.
• In the chart below, simple Mendelian genetics are outlined to understand how this (and ANY autosomal dominant trait) condition is inherited.
