Determine genotype of one of the two parental lines | Homework Help

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)

Phenotype Number
k f B 134
k F B 451
K F B 97
k F b 18
K F b 119
K f B 24
K f b 436
k f b 86
Total: 12,365

What was the genotype (assume it is homozygous) of one of the two Parental lines.
a) k/k f/f B/B
b) k/k F/F B/B
c) K/K F/F B/B
d) k/k F/F b/b
e) k/k f/f b/b

What is the sequence (order) of the three genes.
a) BFK
b) KFB
c) FKB
d) KBF
e) FKB
If someone could show me the steps on how to work backwards and determine 1/2 of the parental genotypes and then the order of genes that would be perfect.
