Why is decreased genetic variation in a species considered a negative impact of genetic technologies?
o It reduces the nutritional value of foods produced by these species,
It produces crops that are more resistant to weed killer.
It makes the species more susceptible to diseases,
It results in foods with less desirable traits,

- asexual organisms: if a disease were to spread in organisms that spread asexually would most likely spread to all of them because of the lack of genetic variation.

>if there were a hundred phones with the same password and you found out that password you can hack into 100 phones.

- sexual organisms: the disease is less likely to spread.

>if there were a hundred phones with all different passwords it would one take way longer to hack into them into overtime they could catch on and change their password (genetic variation)

Decreased genetic variation in species is considered a negative impact of genetic technologies because it makes the species more susceptible to diseases.

Genetic variation is a prerequisite for both natural selection and artificial selection.

In artificial selection, the genetic crosses aimed at obtaining individuals showing desired phenotypic traits are known to decrease the genetic variation.

This decrease in genetic variation may be associated with different problems in offspring across generations (e.g., susceptibility to diseases).

In conclusion, decreased genetic variation in species is considered a negative impact of genetic technologies because it makes the species more susceptible to diseases.
