In maize, liguleless (l) is recessive to having ligules (L), and dwarf (d) is recessive to tall (D). These two genes are linked on chromosome 3. A cross is made and the F2 consisted of the following progeny:
F2 phenotype Number of progeny
Ligules, tall 6156
Liguleless, tall 1344
Ligules, dwarf 1344
Liguleless, dwarf 1156
a. In this cross, are these genes in coupling or repulsion? Why?
b. What were the phenotype and the genotype of the P and F1 generations?
c. Calculate the percent recombination between these two genes.
