When two closely related individuals reproduce, there is more chance of their recessive genes combining and being shown into the individual's pheno type. When the two individuals are not so much related, their recessive genes will cancel out by their dominant genes. thus the offspring will have all the dominant genes which are very likely to be health. But in case of breeding between closely related individuals, they will have higher possibilites of carrying very similar genes. And in this case, the similar genes might be bad on the phenotype. And most cases, the recessive genes that were not apparent in the parent generation will phenotypize by combining due to these inbreeding. thus there are more chance that the offspring will come up with two recessive allelles that are defective and cause some kind of an illness or deformity.

Every animal, no matter how phenotypically 'perfect' is very likely to be carrying deleterious genes. Inbreeding greatly increases the chances of having the same alleles at a loci - thus hugely increasing the chances of genetic disorders.

Inbreeding usually has the strongest affects on reproductive and viability traits - and is never advisable.

That recessive and deleterious traits would be expressed more often by inbreeding than out breeding. Say you have a deleterious, recessive trait in your family. We will call it d, for deleterious. D is not deleterious and dominant.

Inbreeding:

Dd X Dd

===================== no expression of the trait, though carriers are created

In humans - there are many moral and biological problems associated with inbreeding.

In animals, inbreeding reduces genetic diversity (which reduces variation and evolutionary potential), and dramatically increases the chances of disorders.

Inbreeding weakens a species' gene pool. Genetically related individuals will produce offspring genetically similar to themselves, and if those offspring also inbreed, the trend continues. The genetic diversity that results from breeding with others who aren't related is a good thing: if a plague, natural disaster, sudden climate change, or arrival of a new predator threatens a species, genetic diversity makes it more likely that some individuals exist who can adapt to the change.

Some of the risks include blindness and joint deformites in the child.

Deleterious mutations and single gene diseases can be expressed much more readily without being masked by dominant genes of normal trait expression.

When humans/animals interbreed with one another, mutations in the DNA occur, which leads to deformities in the newborn, if the foetus survives.

inbreeding.


What would decrease genetic variation in a population?

When there is low genetic variation in a population the species produced are unlikely to withstand diseases.

What are the affects of first cousins inbreeding?

Inbreeding has the effect of maintaining genetic defects in the bloodline. For example some human populations are descended from a limited genetic stock and have a high incidence of particular types of cancer and other diseases carried by defective genes, such as hemophilia, sickle-cell anemia and cystic fibrosis.


What is an example of Inbreeding?

There are two possible meanings, both relate to the same practice. Inbreeding (which results in inbred offspring, is where very closely related parents mate (this can be in the animal and plant worlds). Extremes of inbreeding can be: brother and sister, father and daughter, mother and son. More common forms of inbreeding occurs between cousins. Inbreeding in animals normally always results in genetic abnormalities, this may not be very apparent with first generation offspring, but if the practice continues can result in some serious (degenerative) disfigurements or diminished mental capacity. However: In plants (as well show animals and livestock) the practice of inbreeding is used extensively to reinforce positive or desirable genetic traits within a breeding line. For example, a cat breeder may breed her pure bred Persian cat with one of the offspring from a previous litter (from the same cat) in order to reinforce a particular genetic characteristic.

What is the basis of inbreeding depression?

Inbreeding depression is the reduced fitness of a population caused by inbreeding. Inbreeding reduces genetic diversity, meaning populations are less genetically adaptable - and greatly increases the chances of genetic diseases and disorders. Inbreeding is most commonly associated with reduced reproductive and viability traits.

Can you breed father bull to daughter?

You could, but you could also risk a calf coming out with a fatal genetic disorder due to inbreeding. Inbreeding is best for purebred herds of which you have a genetic history at your disposal, not a commercial herd which you have no genetic record of.


Which procedure can not be used to increase genetic variation?

If a population dwindles, there is low genetic variation and a species may risk extinction.

What are the instinct against inbreeding?

Genetic diseases and mutations as a result of the pairing of bad alleles.


Is inbreeding in dogs harmful?

Yes - inbreeding in any species is typically harmful to that species. Inbreeding (crossing close relatives like siblings or a parent to an offspring) reduces the genetic diversity of the species and propagates genetic mutations and diseases in the species. Over time, the genetic issues pile up until the offspring are no longer viable - they either do not survive gestation to birth or die prior to reproducing themselves.

What does inbreeding produce?

The act of inbreeding is to procreate with a very close relative. This practice produces inferior organisms because there is not enough genetic variety, which can lead to genetic disorders and weaknesses.
