The evolutionary benefit to this phenomenon is that a male can fertilize multiple females. [6] The male may be reinvigorated repeatedly for successful insemination of multiple females. [7] This type of mating system can be referred to as polygyny, where one male has multiple female mates, but each female mates with only one or a few males. [5]
The male parent of a horse, a stallion, is commonly known as the sire and the female parent, the mare, is called the dam. [1] Both are genetically important, as each parent genes can be existent with a 50% probability in the foal. Contrary to popular misuse, "colt" refers to a young male horse only; "filly" is a young female.
Gorilla Great reed warbler. When two animals mate, they both share an interest in the success of the offspring, though often to different extremes. Unless the male and female are perfectly monogamous, meaning that they mate for life and take no other partners, even after the original mate's death, the amount of parental care will vary. [7]
In some species, the male's contribution to reproduction ends at copulation, while in other species the male becomes the main (or only) caregiver. Plumage polymorphisms have evolved to reflect these differences and other measures of reproductive fitness, such as body condition [ 71 ] or survival. [ 72 ]
Male mammals and birds are usually larger than females, and the sheer size and strength difference makes this very difficult. [1] However, it has been observed in some species, such as squirrel monkeys, patas monkeys, vervets, and captive chimpanzees, that females can “gang up” on males when they are being aggressive.
"The rabbit runs faster than the fox, because the rabbit is running for his life while the fox is only running for his dinner." Aesop [ 32 ] The predator-prey relationship can also be established in the microbial world, producing the same evolutionary phenomenon that occurs in the case of foxes and rabbits.
Technically, polygyny in sociobiology and zoology is defined as a system in which a male has a relationship with more than one female, but the females are predominantly bonded to a single male. Should the active male be driven out, killed, or otherwise removed from the group, in a number of species the new male will ensure that breeding ...
A mule is a sterile hybrid of a male donkey and a female horse.Mules are smaller than horses but stronger than donkeys, making them useful as pack animals.. In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction.
