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.

All progeny will inherit one S allele from the SStt parent and one s allele from the ssTT parent, resulting in Ss (smooth-seeded). For height, all progeny will inherit one T allele from the ssTT parent and one t allele from the SStt parent, resulting in Tt (intermediate height).
