Yes, they are and this is due to the fact that they are both intrusive (a rock having been forced between preexisting rocks or rock layers while in a molten or plastic condition).
Have a similar texture
Similar to granite in composition: rhyolite. Similar to granite in formation: any intrusive igneous rock, such as gabbro or diorite. Somewhat similar in appearance: diorite, granite gneiss, and many others.
Gabbro has less silica than granite.
Granite contains Quartz and Plagioclase Feldspar and Gabbro does not have neither if these minerals in it.
the composition
Have a similar texture
Yes.
the textures are similar yes but gabbro is made up of calcite and olivine while granite contains biotite mica, feldspar, and quartz.

The counterpart of Granite is Rhyolite,the counterpart of Gabbro is Basalt. Gabbro is mafic(Dark coloured) ,Granite is felsic (light coloured) Granite forms from magma of Granitic composition while Gabbro forms from magma of Basaltic composition.
Granite is lighter because its composed of felsic minerals while gabbro is made up of dark ferromagnesian minerals.
gabbro
the composition
Deep underground.
