The sperm carry the chromosomes and they live as long as they live whether or not the ova are present..I don't think there are male sperm and female sperm. Each sperm carries chromosomes X and Y so the timing might not have any effect on the sex of the puppies.
I know a bit about genetics of both humans and animals but not an expert. Would someone let me know if there is a source of info for this.
Maybe Stacy will see this and can add her expertise.. |
