If there is complete linkage with genes Ss (for smooth or wrinkled seeds)and Gg (for green or yellow seeds),what phenotypes would you expect in the offspring of a cross with one heterozygous parent (Ss,Gg),which would all produce all smooth and green seeds,and a homozygous recessive parent (ss,gg),which would produce all wrinkled yellow seeds?
A)smooth green seeds or wrinkled yellow seeds only
B)smooth green seeds only
C)smooth green seeds,wrinkled yellow seeds,smooth yellow seeds,and wrinkled green seeds
D)wrinkled yellow seeds only

With complete linkage, the heterozygous parent (SsGg) can only pass on the alleles as they are linked (SG or sg), and the homozygous recessive parent (ssgg) can only pass on sg. Therefore, the offspring will either be smooth green (SgGg) or wrinkled yellow (ssgg).
