In general, the following characteristics suggest (but do not prove) specific inheritance patterns: Autosomal recessive inheritance: -affected individuals can be born to unaffected parents -if both parents are affected, all children are affected -observable effect of relatedness (consanguinity) -horizontal" inheritance: trait appears at once among several members of one generation (siblings) *** Autosomal dominant inheritance each affected individual has an affected parent -when one parent is affected, transmission to the offspring (on average) *** -two unaffected parents do not transmit...

(For questions 1 – 3) The peppered moth, Biston betularia, experienced a dominant mutation in the cortex gene, located on chromosome 17, about 1819 in England. This mutation is responsible for the melanism mutation that causes dark coloration. The mutation is due to an insertion of a large, tandemly repeated, transposable element into the gene’s first intron. The ‘normal’ (non-mutant) coloration pattern is peppered light grey. 1. Melanism is a Mendelian trait. Refer to the alleles as M and m....
