The effect of butyrate concentration on the expression of the garnet+ gene on the Dp(1;f)LJ9 mini-X chromosome

Butyrate concentration (mm)

MAT87 ± 681 ± 471 ± 364± 6
PAT40 ± 244 ± 538 ± 231± 2

The genotype of the test progeny genotype is y za g53d/Dp in all cases. The origin of the mini-X chromosome is shown on the left (MAT, maternally derived mini-X chromosome; PAT, paternally derived mini-X chromosome). Expression of the garnet gene was monitored as described in materials and methods. Data are given as percentage wild-type garnet eye pigment expression, adjusted for nonspecific effects of buty rate ±SEM, as described in materials and methods.
