In guinea pigs, fur length is controlled by one gene. the f allele generates long fur and the f allele generates short fur. because only one f copy is needed to show the trait, if a guinea pig has the ff or ff allele combination, they will have long fur. if they have the ff allele combination, they will have short fur. look at the data for a guinea pig population to answer the following questions. guinea pig 1: long fur (ff) guinea pig 2: short fur (ff) guinea pig 3: long fur (ff) guinea pig 4: long fur (ff) the sum of the genetic traits in this population is called its
