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.

Answer from: rafoxy35

it make species more susceptible to disease

Explanation:

There are two forms of reproduction: asexual and sexual.

- 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)

Answer from: Quest

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
