What percentage of offspring from are predicted to have a single comb?

The percentage of offspring predicted to have a single comb in a specific species or population will vary depending on the genetic inheritance patterns of that species. In some cases, the inheritance of certain traits may follow Mendelian genetics and can be predicted with more accuracy. However, in many cases, the genetic inheritance of complex traits such as comb type may be influenced by multiple genes and environmental factors, making it more difficult to predict the exact percentage of offspring with a single comb.

If you provide more specific information on the species or population you are referring to, I can try to provide a more accurate estimation.
