Is this what cloning basically is? Asexual reproduction? And are we headed toward making a "perfect" species?  \n*** does this mean humans will become extinct in the not too distant future?

Asexual reproduction\n\n\nAsexual reproduction is the biological process by which an organism creates a genetically-similar or identical copy of itself without a contribution of genetic material from another individual. Bacteria divide asexually via binary fission; viruses take control of host cells to produce more viruses; Hydras (invertebrates of the order Hydroidea) and yeasts are able to reproduce by budding. These organisms do not have different sexes, and they are capable of "splitting" themselves into two or more individuals. Some 'asexual' species, like hydra and jellyfish, may also reproduce sexually. For instance, most plants are capable of vegetative reproduction—reproduction without seeds or spores—but can as well reproduce sexually. Likewise, bacteria may exchange genetic information by conjugation. Other ways of asexual reproduction include fragmentation and spore formation that involves only mitosis.\n\n\nSexual reproduction\n\nSexual reproduction is a biological process by which organisms create descendants that have a combination of genetic material contributed from two (usually) different members of the species. Each of two parent organisms contributes half of the offspring's genetic makeup by creating haploid gametes. Most organisms form two different types of gametes. In these anisogamous species, the two sexes are referred to as male (producing sperm or microspores) and female (producing ova or megaspores). In isogamous species the gametes are similar or identical in form, but may have separable properties and then may be given other different names. For example, in the green alga, Chlamydomonas reinhardtii, there are so-called "plus" and "minus" gametes. A few types of organisms, such as ciliates, have more than two kinds of gametes.\n\nHumans, most animals, and plants reproduce sexually. Sexually-reproducing organisms have two sets of genes for every trait (called alleles). Offspring inherit one allele for each trait from each parent, thereby ensuring that offspring have a combination of the parents' genes. Having two copies of every gene, only one of which is expressed, allows deleterious alleles to be masked, an advantage believed to have led to the evolutionary development of diploidy (Otto and Goldstein).

asexual reproduction doesn't require two partners in order to reproduce...sexual is the opposite.  It requires two creatures of the opposite sex in order to reproduce.

Sexual reproduction speeds the evolutionary process in that it creates larger variance in genetic material between individuals.

the tendency towards a totally homozygotic population is a bad thing as the gene pool will shrink. this means that the population will not have certain members able to deal with the disease and so will therefore die out. A good example of this is banana plantations, where sexual reproduction has been greatly reduced in favour of the banana we all enjoy, and so there is no great genetic variation, and thus if a banana disease were to strike- the plants would most likely all die out.

NO because if the two breed you get what is known as a Ginny it is a animal born of the two speicies but can not produce any offspring because it is sterile.

No, inbreeding is not an optimal method of reproduction, but it has purpose.  It's a natural part of evolution for a species to allow inbreeding.  In order to prevent extincition, small populations need to be able to multiply any way they can until the gene pool can become more varied.

One way to look at biodiversity is to view it as the ammount of genetic variation in a population.  The greater the genetic varation is the more likely it is tha an individual in a population will, at random, have the genetic programing capable of overcoming an obstical.  For example, there are some frogs and some are lighter and some are darker and the population spreads into an area where plant cover is darker than the previous habitat. If there is a preadator that cannot see the darker ones because they blend into the plants better, the preadator will remove the lighter ones.  The darker ones will live and reproduce more offspring than the lighter ones.  These offspring  will be darker like thier parents, and in turn produce even more dark offspring.  The lighter ones will produce fewer and fewer each generation because they are getting eaten. If there was no variation in the population and all the frogs were lighter it is likely that the preadator could eat all the frogs and there would be no future generations.

A group of animals is living in an area - foodsource = nuts. The ones with good crushing teeth will eat lots, reproduce and pass on the crushing design gene. Any with ripping design etc would be unsuccessful in gaining food and thus wouldn't reproduce and pass on the ripping gene. Eventually all members of the species have crushing teeth. Survival of the fittest etc. A lion with blunt teeth would not live long enough to pass on the genes

Not to mention, a 3 percent difference in genetics is a vast difference.  Enough to render a separate and distinct species.

Every living being is trying to reproduce and have successful, surviving, reproducing offspring.  In every reproduction there is a chance of mutation, that one of the genes will function differently.  Often these changes in function cause a defect or a disadvantage, and the creatures with these mutations will die out without reproducing.  However, if the different function results in a significant advantage (making better use of a current food source or enabling the usage of a new food source) than the offspring with that mutation will become more likely to survive and the mutation will become the norm until a new mutation replaces it or environmental conditions change.\n\nThe diversity of life on Earth stems from life forms mutating and making use of all the millions of possible food sources that exist.

asexual reporduction is when the organism simply makes a clone of itself. Sexual reproduction is when there is a joining of sperm and eggs (this can include hermaphrodites because though it is one organism, they have the joining of sperm and egg internally). Both of them have evolutionary value. I think this is a high school question, so your teacher is probably asking which is better at adapting to changing conditions. It is Sexual reporduction because it allows a greater diversity and therefore the species can survive a wider array of conditions. But the sexual reproduction takes a lot of investment to the organism.

Ligers and Tigons are sterile from birth, so there would be no offspring.  However, if one were to unlock the secrets behind genetic recombination, you could sample DNA from both animals and possbly splice a new, third hybrid ... perhaps a Tigron.  Sadly, natural pathways for an enhanced hybrid from these two creatures is impossible.

It is good for a species to utilise varied gene pools (non close relatives) when reproducing in order to continually evolve and strengthen their DNA.  However, it doesn't hurt a particular person to mate with a relative (only if they have kids).
