questions Yes...A male can breed with one testicle..but he should not be bred if he has one testicle..he will produce more males with one testicle (not all males pups, but they will carry the gene) and females who carry the recessive gene..a no win situation.
No, it is not true he will produce all of one sex if he has one testicle. Each testicle contains sperm of both sexes...if these things were so simple, a breeder could have one testicle removed and get only one sexed puppies..
Open fontental can be genetic...the size of the opening can be minor to serious..and I have rarely seem one in a Yorkie over 4 pounds..not that it can not occur, but more likely in the smaller Yorkies. It is not a death sentence or health concern as many vets say...I had a 3 pounder live for 14 yrs with a small one..it is all how big it is..good luck |
