Even outcross programs staunchly rely on the pedigree of a breeding to tell the breeder whether each mating is actually an outcross or not. The best way to gauge whether a cross is or is not an outcross is by calculating the COIs of the parents and the proposed litter.

In short, they have distinguished themselves as being "in the know". Outcross breeding is the breeding together of a male and a female of the same breed who do not share any close relatives. And, obviously, the outcross strain must have the particular characteristic you are looking for. When selfing evolves from outcrossing, homozygosity is almost complete after a few generations (F IS, the inbreeding coefficient, is close to one).This reveals recessive mutations, whose effects were hidden in heterozygous outcrossers (F IS ~0). More alleles were eliminated for all types except beneficial alleles, for which more alleles became fixed. Such plants are fertilized by their own pollen, even before they leave the flowering stage.

Broccoli, cabbage, cauliflower, and kale are all selectively bred descendants of the wild mustard plant. So it's imperative to know the full ins and outs of breeding before producing more horses. Finally, if outbreeding depression occurs inbred seeds germinate better than outbred seeds (Ws>Wo), e.g., Amphicarpaea bracteata (fresh CL seeds, which are nondormant, i.e., seed coat is water-permeable, produced below-ground germinate better than either CH or CL seeds, which have physical dormancy, produced above-ground) (Schnee and Waller, 1986), Arabis fecunda .

The topic of pure vs. mixed is popular and had been cited/brought up a few times recently. B. Sometimes only one outcross helps to overcome inbreeding depression. For example, the percentage of eliminated lethal alleles increased from 70.8% after 75 years to 91.2% after 100 years. The value is computed as ½ (ROutcross-2 + ROutcross-3), where the RXY are taken from the above table. (ii) Cross-breeding: In cross-breeding superior males of one breed are mated with superior females of another breed. Continuously outcrossing was more effective than a single or a few outcrosses. If the selection of the ancestors or ancestor the sire and dam have in common, is an excellent example of the breed, then it would come as no surprise that the offspring would probably be superior.

For example, an outcross between a large body-sized individual with a small body-sized individual may produce a medium sized offspring; the offspring may not be well adapted for parents' environments. This is done for creating newer breeds with better characteristics. Possibly a Roumare son from a different pedigree may pop up. They may assure cross-fertilisation (outcrossing), thereby keeping genetic diversity high. I suppose to answer your question, times where breeding visual to visual might be acceptable would to me be in the following situation.
