In a Species of Wild Lupine Flower,the Smooth Seed Allele

question 8

Multiple Choice

In a species of wild lupine flower,the smooth seed allele (S) is completely dominant over the wrinkled seed allele (s) .If the alleles for height are incompletely dominant,such that TT is tall,Tt is intermediate,and tt is short,what will result from crossing a smooth-seeded short (SStt) plant with a wrinkled-seeded tall (ssTT) plant?

• A) One-half of the progeny will be smooth-seeded and intermediate in height;one-half will be smooth-seeded and tall.
• B) All of the progeny will be smooth-seeded and tall.
• C) All of the progeny will be smooth-seeded and short.
• D) All of the progeny will be smooth-seeded and intermediate in height.
• E) All of the progeny will be smooth-seeded;one-half will be tall,and one-half will be short.
