Canon 1100D has a 12.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor and features Digic 4 processor. On the other hand, Sony A68 has a 24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Bionz X processor.
Sony A68's sensor provides 12MP more than Canon 1100D's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the 1100D and A68 sensor size comparison.

Sensor Size and Resolution Comparison image of Canon 1100D and Sony A68 Cameras
As seen above, Sony A68 has a 1.1x Larger sensor area than Canon 1100D. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Canon 1100D and Sony A68 sensors have been tested by DxO and the results show that A68 has a better overall score of 79, 17 points higher compared to 1100D's score of 62.
