Fine spines (q), smooth fruit (s), and uniform fruit color (t) are three recessive traits in cucumbers, the genes of which are linked on the same chromosome. A cucumber plant heterozygous for all three traits is used in a testcross and the following progeny (recessive alleles from the tester do not show) are produced from this testcross:   Q S T :    3 q  s t:       2 q  s T:    135 Q S t:     140 Q s T:     22 q S  t:     21 q S T:     40 Q s t:      37 Total:     400   Which progeny reflect the parents?
