The figure below is a pedigree that shows the inheritance of a trait, Trait G,in a family. The presence of Trait G in an individual is determined entirely by Gene G.Gene G has 2 alleles;G,which is dominant, and g, which is recessive.
Each individual represented in the pedigree was
assigned a number (shown below the symbol for the individual) for reference. Scientists determined that the Gene G genotype of Individual 20 is gg and that the Gene G genotype of Individual 21 is Gg. based on this information, the scientists
