3. A researcher and her relatives are studying the genetic linkage for three traits in Abominable Snowmen. All three traits are known to be on the largest autosomal chromosome. The three traits are Grinchy versus Gregarious behaviour (G v g), Abominable versus bumbly behaviour (B v b) and Receding fur versus full fur (R v r). Grinchiness is dominant to Gregarious, Abominable is dominant to bumbly and Receding is dominant to full fur. A true breeding Grinchy, Abominable, Furry snowman crossed witha a true-breeding snow-woman who was Gregarious, bumbly and had receding fur. A snow-kid from this cross then mated to a gregarious, bumbly, full furred snowman and had 1,000 progeny who were phenotyped. The little snowmen have the following phenotypes (20 points): Traits Number Generosity Behaviour Fur Genotype 427 Grinchy Abominable Full-fur GBr/gbr 446 Gregarious Bumbly Receding gbR/gbr 11 Grinchy Abominable Receding GBR/gbr 12 Gregarious Bumbly Full-fur gbr/gbr 43 Grinchy Bumbly Full-fur Gbr/gbr 34 Gregarious Abominable
