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)
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
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.
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.
