Prophage
Prophage is the DNA of bacteriophage that is repressed for lytic functions and is maintained in the host bacterium in a stable state. Te phage genome is integrated into DNA of its bacterial host and may be replicated along with the host DNA, as in the case or bacteriophage lambda or may be maintained as extrachromosomal DNA, as in the case for bacteriophage, lambda P1

Tow genes R and y are located very close on the chromosome linkage map on maize plant. When RRYY and rryy genotypes are hybridized, then F2 segregation will show
Higher number of the recombinant types
Segregation with expected 9:3:3:1 ratio
Segregation is 3:1 ratio
Higher number of the parental types
