Horses can breed with Przewalski's horse to produce fertile hybrids. Mule, a cross of female horse and a male donkey. Hinny, a cross between a female donkey and a male horse. Mules and hinnies are examples of reciprocal hybrids. Kunga, a cross between a donkey and a Syrian wild ass. Zebroids. Zeedonk or zonkey, a zebra/donkey cross. Zorse, a ...
A creeper is a fictional creature in the sandbox video game Minecraft.Creepers are hostile mobs (mobile non-player characters) that spawn in dark places.Instead of attacking the player directly, they creep up on the player and explode, destroying blocks in the surrounding area and potentially hurting or killing the player if they are within the blast radius.
[2] [3] Subsequent generations are called F 2, F 3, etc. The offspring of distinctly different parental types produce a new, uniform phenotype with a combination of characteristics from the parents. In fish breeding, those parents frequently are two closely related fish species, while in plant and animal breeding, the parents often are two ...
Inbreeding in fish is the mating of closely related individuals, leading to an increase in homozygosity. Repeated inbreeding generally leads to morphological abnormalities and a reduction in fitness in the offspring. In the wild, fish have a number of ways to avoid inbreeding, both before and after copulation.
In video games using procedural world generation, the map seed is a (relatively) short number or text string which is used to procedurally create the game world ("map"). "). This means that while the seed-unique generated map may be many megabytes in size (often generated incrementally and virtually unlimited in potential size), it is possible to reset to the unmodified map, or the unmodified ...
Unless there is strong selective pressure, outbreeding depression can increase in further generations as coadapted gene complexes are broken apart without the forging of new coadapted gene complexes to take their place. If the outcrossing is limited and populations are large enough, selective pressure acting on each generation can restore fitness.
Hormonal treatments can advance spawning by two to three weeks. [5] Manipulating photoperiod can alter spawning time by over four months and is cheap and straightforward to achieve. [5] Broodstock managers can use or select for traits such as fast growth rates or disease resistance over generations to produce more desirable fish. [15]
The word "semelparity" was coined by evolutionary biologist Lamont Cole, [4] and comes from the Latin semel ('once, a single time') and pario ('to beget'). This differs from iteroparity in that iteroparous species are able to have multiple reproductive cycles and therefore can mate more than once in their lifetime.
