1 answer:

8 0

Answer:

specificity is an important criteria for screening and diagnostic instruments, the specificity of a test reflects the probability that the screening test will be negative among those who, in fact, do not have a disease.

A test that is 90% specific will identify 90% of patients who do not have the disease. Tests with a high specificity (a high true negative rate) are most useful when the result is positive. A highly specific test can be useful for ruling in patients who have a certain disease.

How are genes and proteins similar to homologous

Vinil7 [7]

Homologous traits of organisms are due to sharing a common ancestor, and such traits often have similar embryological origins and development. This is contrasted with analogous traits: similarities between organisms that were not present in the last common ancestor of the taxa being considered but rather evolved separately.
