A geneticist makes a cross between two homozygous strains (lines) of maize with three different mutations. The specific genes are as follows. F = striped leaf, B = a bronze aleurone and K = crinkled leaf. For symbols, you can use a capital to indicate the dominant (WT) allele. He then backcrosses the F1 to a homozygous recessive tester stock. (F = wild type, f = fine stripe; B = wild type, b = bronze aleurone; K = wild type, k = crinkled leaf)
