What are some of the genetic problems you might encounter during selective breeding?

Answer 1

um i really think that selective breeding is really wrong people thinks its funny but its really sad because selective breeding is abusing animals and maybe someone can make a illness and kill people etc. but i think its very wrong

Answer 2

personally, I think selective breeding is helpful. It refines the breed; bringing better business to the breeder, and a better animal to the future owner, providing the strongest or sleekest or reddest animal possible.

Answer 3

Selective breeding based on external characteistics is somewhat less than a hit and miss affair. If you know the genetics, the breeding usually goes better. Selective breeding is not always for better breeds -- or maybe it is. What's better? People have selectively bred a strain of mouse that has an epiletic fit when music is played -- is that better? OK, for the reseachers, maybe that is better. Selective breeding does not always make what you want. Problems arise.

Answer 4

Selective breeding can be used to fix desirable characteristics in a breed population.

Unfortunately it can also inadvertently fix undesirable traits as well which then have to be removed from the gene pool. Examples are HYPP in Quarterhorses, dwarfism in Hereford cattle, hip dysplasia in certain Dog Breeds.

There is also the possibility that the breed organization specifically selects characteristics that result in detrimental effects on the breed even though it produces a "desired" appearance. Examples are difficulty giving birth, weakened or

diminished facial bones, etc.

Answer 5

Some genetic problems that can arise during selective breeding include inbreeding depression, genetic disorders caused by deleterious recessive alleles, and reduced genetic diversity within the population leading to vulnerability to diseases and environmental changes.

Answer 6

Either inherited traits from parents or, the selected adaptation will prevent the animal for surviving.
