We kept back a black Dangus (Angus momma/ dun Dexter sire) that my hubby liked. Bred her to Selby (dun) Dexter bull and now have a DUN 3/4 Dexter 1/4 Angus bull calf! I was kinda surprised...guess the heifer carried dun from her sire??

Hi Rhonda,
That's correct. Since your Dangus cow's sire was dun (b/b), she inherited a dun gene (b) from him and a non-dun gene (B) from her Angus dam, making her B/b. When you breed that Dangus cow (B/b) to a dun bull (b/b), her calf has a 50% probability of inheriting the dun gene from her (since she is heterozygous for dun, B/b) and a 100% probability of inheriting the dun gene from the dun bull (since he is homozygous for that gene, b/b).

hey, rhonda, or in other words, the cow was half dun, half black, the bull was all dun, calf has 50% chance of being either. She got the dun gene from both sides and is therefore dun herself, dun being a recessive gene and needing the pair of genes the same to look dun. ;D c.
