How is a genus different froma species? Can animals of thesame genus interbreed?
Sheep and Goats are a different genus, yet they have been known to interbreed. So what exactly is a genus and a species?
Animals are classified into groups based on similarities between them. In its simplest form, this classification has seven levels - kingdom, phylum, class, order, family, genus and species. A kingdom is the broadest level of classification, whilst a species is the smallest (except for subspecies, but you needn't worry about that for now). An animal's or plant's genus and species, used together, form its scientific name, sometimes called its 'Latin name' although ancient Greek is also used, and sometimes words are just 'Latinized', as when a species is named after a person or place. The scientific name can be used anywhere in the world to refer to the same animal, which will of course have different common names in different languages. Here is the classification of the lion, as an example: Kingdom - Animalia Phylum - Chordata Class - Mammalia Order - Carnivora Family - Felidae Genus - Panthera Species - leo Thus, the lion's scientific name is Panthera leo. An animal's closest relatives will be in the same genus, meaning that the closest relatives of the lion are the tiger (P. tigris), jaguar (P. onca) and leopard (P. pardus). These animals shared an ancestor with each other more recently than they did with any other animals. The fewer levels of classification two species share, the more distantly related they are, and the less genetic material they share. This is why animals within the same genus can usually interbreed, whilst interbreeding becomes impossible beyond family level. Even when animals of the same genus interbreed, the offspring are likely to be sterile, because the parent species have different numbers of chromosomes (this means the hybrid cannot produce functional sex cells). Where two species can interbreed and produce fertile offspring, it shows that they are very closely related. Though goats and sheep are in different genera (Capra and Ovis respectively), they both belong to the family Bovidae. Inter-genus hybrids are rarer than those between animals of the same genus, but they can and do occur, though the offspring are more likely to be sterile, and are more difficult to conceive in the first place - in the case of goat/sheep hybrids, many are stillborn.
What was the genus of thecommon ancestor to hominidsand chimpanzees?
Just like e.g. prehistoric fish branched into fish and amphibians (prehistoric fish being classified in the same class as fish), the genus Homo and Pan mst have branched off a previous genus... which? Could it be classified within either Homo or Pan? What I'm trying to point out is that just as primordial fish evolved branched into two classes one of which was the continuation of primordial fish, either the Pan and Homo (or Australopithecus) genus must be the continuation of the preexisting genus of which the common ancestor was a member.
No remains have been found to be described, so it doesn't have a name. <> It couldn't be classed as /Homo/. That's because /Australopithecus/ is more closely related with that genus than chimps are. It also couldn't be classed, under the existing rules, as /Pan/ unless you reduced the present /Homo/ genus concept to being a species of that genus.
What are some genus names ofgram positive bacteria?
I need as many genus names for gram positive bacteria as you guys can think of. I need to come up with a genus name for my bacterial unknown and I don't know to many different genuses. Let me know some names so I can research and figure out what mine is. To narrow it down, it is a rod and I believe it is non-endospore forming. Thanks for your help. Oh and they dont have to be medically significant, but I thought this would be a good area to post my question.
WOW. I wish i could help but I got lost early in the question. Hope you get some help.
