Indra's chakra is the sole reason why his descendants can awaken the Sharingan. It's more than just simply inheriting the eye. That's why genetics come in to play and it's why certain Uchiha end up developing different abilities when they go beyond the 3T (MS). The chakra which awakens the Sharingan is the same thanks to Indra, but the varied genetics contributes to things like Kamui arising.
