artificial selection
The cross that will produce only horned Roan offspring in cattle is the red bull with the white cow. However, these offspring would be able to create either red, white, or Roan.
When a horse and a donkey mate and they create a mule. The mule is unable to create offspring, thus a post-zygotic barrier
Elephants reproduce sexually. It takes both a male and a female elephant to produce an offspring one. They cannot simply [example] break off a toe to create one, and thus it's called Sexual Reproduction.
The Braford breed is a result of crossbreeding Brahman with Hereford. The breed has been created in such a way that resulting offspring of this F1 cross no longer have hybrid vigour (or less so than the initial Brahman-Hereford cross), and thus create cattle that can be registered as purebred Braford cattle.

No. Roosters and hens can be of different breeds to create offspring, just like different breeds of cattle, sheep, goats and pigs can breed to create offspring.
Sexually- meiosis occurs to produce offspring Asexually- parent cell clones itself to create 2 identical offspring

either produce offspring or produce hormones

Offspring and wastes.
Nothing. Skunks produce offspring through sexual reproduction and bananas create seeds. If you tried crossing them the skunk would probably eat the banana.
The goal of artificial selection is to produce offspring with desirable qualities. For example, some dog breeders use artificial selection to mate two dogs who are purebreds. In this manner, the offspring will also be purebred. Similarly, dog breeders may use artificial selection to create "cute" hybrids. An example is the labradoodle which has a shape similar to that of a labrador retriever but the curly hair of a poodle.
Heredity
Horses mate for the same reason that all other animals including humans mate. It is to create offspring and keep a particular species alive. Horses are breed typically to sell or use for show.
Sexual reproduction is when you need two beings to reproduce. for example: Humans need the sperm and the egg to create a baby. Asexual reproduction is when the being has both sex cells within it's body it does not need a partner to create an offspring. for example: amoebas.
