Hi, We have a 12 week old pup. (got her at 9 weeks). Maya is a tri-colour. We are very happy with her. She's a bundle of energy and fun. Don't know what else to say right now but hope to get to know some other people and read lots of advice.
Most people incorrectly use the terms dominant and dominance with regard to dogs. Here is a good blog post by Dr. Sophia Yin on the topic.

Welcome to the forum.
I think Lark is a lovely name. Whatever she is you love her so it doesn't really matter. She looks a very interesting mix.
She obviously needs quite a bit of attention given to her training.
Lots of dogs don't get on with cats but with Basenjis it's easier when they grow up with them - it'll probably be harder work at Lark's age.
Work especially hard on stopping the nipping as somebody could get hurt. Try to make sure you don't get her over excited - be calm around her and she'll learn to be calm around you.
