What are the genetic dangers of inbreeding?
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.

Thanks for the feedback!
Inbreeding is breeding between close relatives, whether plant or animal
DEATH! AND PUPPIES! i just think puppies are cute. :)
Nobody really knows. The educated guess is that: Genetically engineered plants are not dangerous to eat. The DNA of the altered plant or animal cannot directly affect our ow…n DNA. All the food we eat is made of cells, which have genes. It does not make any difference if the genes came from a wild plant, from a plant crossbred by farmers, or a plant engineered in a lab by geneticists. The function of the proteins that the DNA codes for is usually not dangerous directly to humans, but can have ecological ramifications. An example would be the proteins that BT corn produces, affecting the larval stage of many arthropods in the ground and in the ground water surrounding any BT crop, field or anywhere unprocessed BT corn is stored or used.
yes it is. there all inbread. (ROB TEMPEST)
An individual who cannot produce phenylalanine would not be viable so I believe what you are asking about is Phenylketonuria which is a genetic disorder found is infants who c…annot properly digest phenylalanine (they can manufacture it). Hospitals test for this disorder in newborns because it is imperative to place babies that test positive on a strict diet to prevent the mental retardation that is associated with the disorder. Early intervention results in a nearly normal life.
In the sense that they are all human, yes.
No , it is a non toxic noble inert gas, but you can't live in it because of lack of oxygen
Inbreeding weakens a species' gene pool. Genetically related individuals will produce offspring genetically similar to themselves, and if those offspring also inbreed, the tre…nd 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.
When humans/animals interbreed with one another, mutations in the DNA occur, which leads to deformities in the newborn, if the foetus survives.
Why does inbreeding increase the rate of genetic defects and is this why a species needs a minimum population to avoid extinction... If so how do species arise from what must be a small sample?
Cross this set of alleles. Aa X AA The a is a deleterious genetic defect and in a small population the carriers of this defect will breed with each other in a probabilistica…lly greater number. Why do species rise from a small sample necessarily? They do not always do that. A geographically isolated species may be very large. Regardless, look to the alleles I showed you. Probabilities are all. Say this cross in our small population.I showed these alleles existing. Aa X Aa This cross yields 1/4 AA, and probabilistically a small population could get out of deleterious trouble; or they could, after a time, go extinct. Lots of random events in the history of life.
It is FAR more dangerous to inbreed cattle than to crossbreed them. Inbreeding exposes genetic abnormalities that would only be exposed if a hetero cow was crossed with a hete…ro bull for a particular genetic abnormality. Inbreeding is only done if you are mating siblings, daughter to sire, son to dam, cousins, son to granddam, daughter to grandsire, etc. It can also kill your herd as far as productivity is concerned because the more you inbreed, the worse-quality your cattles' offspring will be. Crossbreeding on the other hand, occurs when you breed a different breed a bull to a breed of cow: for instance, breeding a Black Angus bull to a Hereford cow. The offspring that comes with this cross is the exact opposite of inbreeding: you get a very vigorous, high-productive calf that will excel above either of his parent's breeding in the feedlot or in the breeding herd. Generally cross-bred animals live longer and are much better-quality than those breeds that it came from. If you want a herd with great-quality cattle, use cross-breeding.
cause it's just awesome like that
No, because the crops are just grown faster than normal.
No it does not because you would be getting the same exact cells that your family already had. You would only get variation when you have a mixture of unrelated cells.
Because we're a long way away from knowing enough about it. An introduced change might move away and turn into something unforeseen that will cause trouble for us.
There may be no danger with genetically modified foods, but many people are concerned that the effects of eating GMO foods is not known. While many studies show GMO food is sa…fe, others point to anecdotal evidence suggesting that they may cause health issues.
