Why do mapping experiments become less accurate when the distances between genes become large? View Available Hint(s) Why do map
Otrada [13]

Answer:

Multiple crossovers are more common.

Explanation:

Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.

A mapping experiment refers to an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).

This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.

In mapping experiments, if the genetic distance increases, there would be a consequential increase in multiple crossovers causing a recombinant with an odd number of crossovers and a parental combination with an even number of crossover events by switching it back.

Hence, mapping experiments become less accurate when the distances between genes become large because multiple crossovers are more common.

Gennadij [26K]

Answer:

Decreased use of pesticide.

Explanation:

If there is only one answer the one above^ is the one that I would go with.

The questions asks about a GMO that makes a plant less appealing to insects and is more resilient to weed killing chemicals.  Because it is less appealing to bugs to eat, there would be less of a need for pesticides.  Personally, I do not feel as though there is enough evidence in the question to draw a conclusion on the other answers provided.

Further Explanation:

Scientific investigations usually begin with observations. These are typically something that would catch the researcher’s attention. Then, the scientist comes up with a hypothesis which is a testable explanation for the phenomenon or what’s occurring a prediction is usually made based on the hypothesis.

A prediction of the outcome is usually made based on the hypothesis, after which it is tested via an experiment. The scientist then use the results to make new hypotheses or predict certain outcomes.
