- 1. Multiple ChoiceA calico cat shows both the traits for orange fur and black fur. What kind of allele expression is this?Incomplete DominanceCodominanceIndependent assortmentRecessive inheritance
- 2. 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
- 3. Multiple ChoiceThis type of inheritance pattern is a MIXTURE of both traits.incomplete dominancecodominancecomplete dominancerecessive pattern
- 4. Multiple ChoiceIf a man with blood type A and a woman with blood type B produce an offspring, what might be the offspring’s blood type?AB or OA, B, or OAB onlyA, B, AB, or O
- 5. Multiple Choice
Which of the following pairs of genotypes result in the same phenotype?
BO and OO
BB and AB
BB and AA
BB and BO
- 6. Multiple ChoiceThis type of inheritance pattern shows BOTH traits in possible offspring:complete dominanceincomplete dominanceco-dominanceIndomitable
- 7. Multiple ChoiceWhen two or more alleles for a trait exist in a population. Ex: Different hair colors or blood typesSHAZAM!Multiple GenesMultiple AllelesPolysaccharide
- 8. Multiple ChoiceThere are three common alleles for the gene that controls blood type. These are A,B, and O. Their Dominant/recessive relationship is:A and O are codominant and B is recessiveO is dominant and A and B are corecessiveA and B are codominant and both are dominant to OB and O are codominant and both are dominant over A
- 9. Multiple ChoiceWhat is a possible phenotype of a child that results from a woman with type AB blood and a man with type A blood?OOtype OAAtype A
- 10. Multiple ChoiceAn orange jellyfish mates with a green jellyfish. All of the offspring are blue.complete dominanceincomplete dominancecodominance
- 11. Multiple ChoiceTwo traits are blended or create a "new" traitcomplete dominanceincomplete dominancecodominance
- 12. Multiple ChoiceHow many alleles does an individual have for each trait?1234
- 13. Multiple Choice
What type of inheritance do two alleles have if their traits blend together?
Incomplete Dominance
Co-Dominance
Mendelian Inheritance (Complete Dominance)
Homozygous Inheritance
- 14. 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
- 15. 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.
- 16. Multiple ChoiceSnap dragon color is a incomplete dominant trait. A red flower (RR) is crossed with white flower (rr)? What color are flowers that are Rr?RedRed and WhiteWhitePink
- 17. Multiple ChoiceIn chickens, feather color is codominant. If a black chicken BB is mated with one that is black and white (BW) what are the chances of having a chicken that is black and white?50%0%25%100%
- 18. Multiple ChoiceIn Andalusian fowls, black individuals (BB) and white individuals (bb) are homozygous. Heterozygous individuals are grey (Bb).
What is the genotype ratio for a cross between a grey fowl and a white fowl?2 BB: 2 Bb: 0 bb0 BB: 4 Bb: 0 bb0 BB: 2 Bb: 2 b1 BB: 2 Bb: 1 bb - 19. Multiple ChoiceIn Andalusian fowls, black individuals (BB) and white individuals (bb) are homozygous. Heterozygous individuals are grey (Bb).
Cross a black fowl with a white fowl. What is the phenotype ratio?4 black: 0 grey: 0 white2 black: 2 grey: 0 white0 black: 4 grey: 0 white0 black: 2 grey: 2 white - 20. 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
- 21. 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 - 22. Multiple ChoiceIn some carnations, flower color exhibits codominance. When crosses, Red (R) and white (W) flowers make speckled flowers (RW) that show both colors.
