Help me understand coat colour DNA test results?

[Toothpick134]

Hello everyone,

Greetings from the UK. I wanted to ask someone who may have experience in breeding French Bulldogs. I have recently had my French Bulldog girl (Phoebe) DNA tested for coat coat colour. She herself is of Black coat, KC Registered with excellent bloodlines. The results were as follows: n/n, n/At, n/a, B/B, D/d, E/E, EM/EM, n/KB, N/S. (please see attached image for the results with some explanations.)

I have a basic understanding of genetics and Dominant/Recessive genes, and have tried watching many youtube videos explaining it. I would like to ask your opinion in understanding the results.

My question is: when picking a stud based off of his DNA, what are my options with regards to possible offspring coat colours my dam can produce? What DNA should I look for when picking a stud and what are the possibilities in terms of coat colour of offspring?

Thank you for reading my post, I would really appreciate any help.

All the best!

Welcome! IMO, breeding should be based on health, not what colors will be produced. Health testing needs to be done.

Yes I agree and I can assure you all health tests have been done or are scheduled to take place, my question was regarding colour/genes because that is one of the things I'm having trouble understanding.

Because male and female each have dominant and recessive genes, I believe you would need to see the chart for prospective males. Without that, it could be any combination.

I am no gene expert, but you also need to see the sires DNA too. Black is a dominate color, so if both carry the black gene you are more likely to have black than any color, but it doesn't mean they all will be black. There was a good chart out there and I used to have a copy of it, but can't find it, but it's on the web.
