Tallness (T) in snapdragons is dominant to dwarfness (t), while red (R) flower color is dominant to white (r). The heterozygous condition results in pink (Rr) flower color. A dwarf, red snapdragon is crossed with a plant homozygous for tallness and white flowers. What are the genotype and phenotype of the F1individuals?


A)ttRr–dwarf and pink


B)ttrr–dwarf and white


C)TtRr–tall and red


D)TtRr–tall and pink


E)TTRR–tall and red


Answer:

D)TtRr–tall and pink

    Gene S controls the sharpness of spines in a type of cactus. Cactuses with the dominant allele, S, have sharp spines, whereas homozygous recessives s cactuses have dull spines. At the same time, a second gene, N, determines whether cactuses have spines. Homozygous recessive nn cactuses have no spines at all.


    The relationship between genes S and N is an example of


    A) incomplete dominance.


    B) epistasis.


    C) complete dominance.


    D) pleiotropy.


    E) codominance.

    B) epistasis.
