If you have F1 Goldendoodle puppies, they inherit genes from each of their parents, meaning they'll usually have some furnishing. However, when you're breeding second generations of doodles, it can become more complicated. In this case, an adult f2 Goldendoodle can either inherit 50% of each parent's genes, or 25% of one parent and 75% of the other parent. In these cases, you'd end up with an f2b straight coat Goldendoodle. In other words, the dog would have straight hair (from the Golden Retriever genetics)
