When a female is in heat any male will mount her and it does not matter if he is the best, just the closest.

Except harem animals will have a dominant male who would chase off any lesser male who attempts that.

They can try. While they are chasing one they are not breeding and another scrub can mate with "their" female.

Not to mention you can have cases like the recent one in SA where the old bull was sterile and was killing any of the young bulls who could have bred the does.

It maintains but even over time the herd shows almost no improvement and what there is is of the land race variety.

Give the same bunch of animals to a farmer and in a quarter of the time you gave the wild ones he will have turned them into fine stock.

Animals just do not behave as he said they do.
