For many, who are without Knowledge of 'Domestic Animal Husbandry', you did very well as a primer/intro for principly, the 'Urban citizen'. So many are so lacking, in awareness of the relationship between the 'Farmer -- Rancher -- Gardener, and His/Her care and comfort for all creatures under their management. Thank you 'Jess Smith' -- Lake Geneva HS - 1959.
but these two are interbreeding between species , so they are exception actually because mostly species interbreed will be infertile or can't even take birth due to little difference in their chromosome so ultimately their gametes will be differ too. female ova doesn't accept sperm even vitro methods (as we know it through the definition of species) If you are talking about inbreeding between races then obviously their offspring will be fertile like if you will marry with Japanese, Chinese and Korean then you will have fertile baby ^_^,
