So, this is sort of a long post but hopefully you can keep up. First of all, and most importantly I have read in several places that a male kitten's color can only be determined by the dam's coloration or a dilution thereof. In my own personal experience, I have seen otherwise, and I will explain why- I had a cinnamon pointed female cat give birth to a male tuxedo cat and his black is very black. I saw her with a male tuxedo cat that looked very similar to Binx (the baby). The fact that she had a dominate colored kitten tells me the color here must have come from the father because brown would have been the dominate color here not black. She also had one blue swirl pattern tabby male and two blue tortoiseshell females. If a dilute color (cinnamon) cannot produce a dominate color (black), then the black gene must have come from the father. This was years ago.
I have also recently had a brown tabby/tortoiseshell cat give birth to two blue babies that look exactly like the blue swirl tabby cat I mentioned earlier. They are both male and I presume him to be the father. She also had one male dark colored tabby (like her but without the tortie markings) and one blue tortoiseshell female. If anyone has similar experience or additional information on this topic, please feel free to share or tell me how I may be wrong.
