Selective breeding narrows the organism’s gene pool, causing harm to
the organism overall.
When humans in breed plants, the plants may get genes that cause it to
be more prone to diseases and could wipe out an entire population. When
animals are selectively bred, they often get health problems such as cancer,
organ problems, orthapedic problems, and more. When humans mess with
genetics the organisms do not breed true and have no variation. Although
selective breeding can ensure food security, changing genes may cause the
foods to go extinct. Selective breeding is not safe or right because it can
harm the organism and narrow the genes that are passed on.

Selective breeding narrows the organisms gene pool causing, harm to
the organism overall. Selective breeding is the process by which humans
breed other animals and plants for a particular trait.
Selective breeding may cause serious health problems to the animal
such as skin problem, blood disorder, heart disease, cancer, immune system
diseases, hearing and vision problems, etc. Selective breeding eliminates
variation in a population and has no control of genetic changes or mutations.
This means mutations may occur at any time during the process cause
glitches and unexpected changes. Selective breeding doesn’t just affect the
animals it may also affect plants. People use selective breeding on plants to
get a higher-yield. This means that using this process will result in more
food than normal. However, during this process plants may stop growing.
Bananas are growing extinct for a while due to selective breeding. However,
providing genetic blueprints of inedible wild varieties can delay extinction
to bananas.
While there are many cons to selective breeding, there may also be
some benefits. Plant breeding produces more crops and crops take in CO2.
Less CO2 in the air will be beneficial to humans. Also selective breeding has
allowed genes from animals and plants to evolve mechanisms to deal with
hotter environments. However, these mechanisms could fail or glitch
creating a mutation.
In conclusion selective breeding is harmful to the animal by causing
mutation, diseases, and loss of genetic variation.

B. Selective breeding narrows the organism’s gene pool causing harm to

Selective breeding narrows the organism’s gene pool causing, harm to
the organism overall. Selective breeding may change desirable traits into
undesirable ones, it could also lead to domestication which could be bad,
depending on the organisms environment. I say this because selective
breeding is a gamed chance, there is no way to tell what traits will show
through. Another example is that bananas are more vunerable because of
selective breeding, using selective breeding in bananas has bred out the
factors in a banana that can protect it against environmental factors. A lot of
purebred dogs are at risk of health problems because of selective breeding.
Over time interbreeding in a breed breaks out the factors in a dog that helps
it protect against health problems or it breeds to form a physical trait that
can lead to health problems. The other argument is that, selective breeding
allows us to improve an organism to have the best genes possible for life.
This is wrong because as I stated before genetics is a game of chance, you
have no way to know, also it could cause something potentially harmful in
an organism. Yes, selective breeding can be good but overall it eliminates
genetic variation, and has more negative impacts on a species than positive.
That is why I believe that selective breeding is harmful to the overall
organism.

Selective Breeding is unhealthy and narrows the organisms’ gene pool causing
harm to the organisms overall.
GM breeding is a type of selective breeding. GM breeding is worse than natural
breeding and causes plants to lose variation. Craig Holder, director of The Natural
Institute, said that natural breeding crosses only closely related organisms. While, GM
breeding just slaps together genes up to 15 wildly different genes from different
sources. Joe Mendelson, director of Center for Food Safety, said that irregular cross
pollination the species have to be the same. With GM breeding you can take any gene
from any species and splice it into a crop.
Two articles, What are the Pros and Cons of Selective breeding, and Limitations +
Advantages of Selective breeding, both say that selective breeding eliminates the
variety of certain organism groups. Not only can selective breeding cause less variation,
but it can also cause diseases to be more vulnerable to organisms. In an article, Yes,
We’ll have no Bannas, it says that the selective plant breeding made the bananas
vulnerable to diseases such as Black Sigotka. The disappearance of bannas should be a
wake-up call to reckless genetic mutation. In another article, Limitations + Advantages,
it says that selective breeding can be prone to diseases that not normally would be a
problem to a natural population.
Lastly, selective breeding can cause diseases to be prone to that type of breeding.
For example, in an article, Dog that Changed the World and Selective Breeding
problems, it says that different dog that breeded for certain things work against them.
An example are dogs that breeded to be small can harm them because they can’t warm
themselves up quick enough. Other dogs that have excessively wrinkled skin can cause
skin infection, dogs that are flat faced have breathing problems, blood hounds suffer
eye irritation, large dogs are prone to heat prostration because they can’t cool down,
German Shepherds may inherit a disease that cripples the spinal cord, weaken it, and
eventually paralyze it, cancer is strongly influence by genetics, etc.
In another article, What are the Pros and Cons of Selective Breeding, it states that
selective breeding might help to hasten good traits of the evolutionary process, but it
can do nothing about mad traits. Yes, selective breeding does help feed the mouths of a
growing population by breeding new plants that grow food faster, efficient, and
plentiful. but it can make the plants an easier target for diseases, and can bring out mad
traits that weren’t a threat before. It is not considered a triumph if you selectively
breed with the intention of feeding a growing population, but instead kill out the plant
and make it near to extinction, just like we humans did with bannas. Selective Breeding
not only brings out bad traits from a gene pull, but it also messes up the natural
evolutionary process in which can result in extinction.
