D) 1:2:1

11. The phenotypic ratio of the F2 generation is

A) a cross between parent plants whose flower color is different from that of their offspring

12. Heterozygous pink snapdragons are an example of intermediate inheritance in plants. These pink- flowered plants may be produced as a result of

A) They have two alleles that are codominant.

13. Which is a true statement about people with the genotype IA IB for blood type?

C) incomplete dominance

14. When roan cattle are crossed, 25% of the offspring produced will have white coats, 50% will have roan coats, and 25% will have red coats. What do these results illustrate?

B) 50%

15. If two roan cattle are crossed, what percent of the offspring are expected to show the parental phenotype for coat color?

D) codominance

16. Crosses between white-coated cattle (CW CW) and red-coated cattle (CR CR) produce roan offspring (CR CW). This type of inheritance pattern is known as

A) Intermediate inheritance involved alleles that were not clearly dominant or recessive.

17. A cross between two plants that have pink flowers produced plants that have red, pink, or white flowers. Which is the most likely explanation for these results?

A) white and blue petunias

D) A, B, AB, or O

2.Which of the blood types in the ABO system may safely be given to a person with AB blood

C) 50%

9. Barbara is expecting another child. What is the probability that the new baby will be colorblind?

B)determined by multiple alleles

A mother with type B blood and a father with type A blood have four children, each with a different blood type. The best explanation for the occurrence of the four different blood types of the children is that blood type is
