What is a mule in biology?
A mule is a sterile hybrid of a male donkey and a female horse. This creature stands smaller than horses but stronger than donkeys, making it useful as pack animals.
Questions about Hybrid (biology)
Short answers, pulled from the story.
When was the oldest-known animal hybrid bred by humans created?
The oldest-known animal hybrid bred by humans is the kunga equid hybrid produced 4,500 years ago in Umm el-Marra, present-day Syria.
How does hybridization affect plant evolution?
Hybridization is a particularly common mechanism for speciation in plants and is now known to be fundamental to the evolutionary history of plants. Whole genome doubling has occurred repeatedly in plant evolution when two plant species hybridize.
Why do conservationists worry about genetic pollution from hybrids?
Genetic erosion from monoculture in crop plants may damage gene pools of many species for future breeding. Hybridization could potentially threaten rare species or lineages by swamping genetically pure individuals with hybrids.
Which yeast produces lager beer through hybridization?
Production of lager beers is known to be carried out by yeast Saccharomyces pastorianus, a cryotolerant hybrid between Saccharomyces cerevisiae and Saccharomyces eubayanus.
