- 8. Multiple ChoiceA breed of chicken shows codominance for feather color. One allele codes for black feathers, another codes for white feathers. The feathers of heterozygous chickens of this breed will be:all blackall whiteall grayspeckled black and white
- 9. Multiple ChoiceThis type of inheritance pattern shows BOTH traits in possible offspringcomplete dominanceincomplete dominanceco-dominancedominant pattern
- 10. Multiple ChoiceA roan cow shows co-dominance in fur color (orange and white). What is the phenotype ratio expected if a roan cow and a roan steer mate together?4: Orange and White1: Orange : 1 White2 Orange: 2 Orange and White: 0 White1: Orange: 2 Orange and White: 1 White
- 11. Multiple ChoiceHow are Incomplete Dominance and Co Dominance different than a normal Mendelian cross?There is no differenceThe heterozygous genotype has a unique phenotypeThere is no heterozygous genotypeThere is only one phenotype regardless of genotype.
- 12. Multiple ChoiceThis type of inheritance pattern is a MIXTURE of both traits.incomplete dominanceco-dominancecomplete dominancerecessive pattern
- 13. Multiple ChoiceIn some carnations, flower color exhibits codominance. Identify the correct genotypes for red, white, and speckled carnations.Red = RR, white = rr, speckled = RrRed = RR, white = WW, speckled = rwRed = RR, white = ww, Speckled = RwRed = RR, white = WW, speckled = RW
- 14. Multiple ChoiceIn some carnations, flower color exhibits codominance. When crosses, Red (R) and white (W) flowers make speckled flowers (RW) that show both colors.
Complete a cross between 2 speckled flowers and find the genotype ratio.0 RR: 4 RW: 0 WW2 RR: 2 RW: 0 WW1 RR: 2 RW: 1 WW0 RR: 2 RW: 2 WW - 15. Multiple ChoiceIn some carnations, flower color exhibits codominance. When crosses, Red (R) and white (W) flowers make speckled flowers (RW) that show both colors.
