If a trait A exists in `10%` of a population of an asexually reproducing species and a trait B exists in `60%` of the same population, which trait is likely to have arisen earlier ?

A trait B which exist in `60%` population of an asexually reproducing species, must have arisen earlier than trait A.
Because in asexually reproducing species there are chances of appearance of very few new traits due to small inaccurancies during DNA copying. So, populations having trait A have arisen later.

Suppose that the reliability of a HIV test is specified as follows: Of people having HIV, 90% of the test detect the disease but 10% go undetected. Of people free of HIV, 99% of the test are judged HIV-ive but 1% are diagnosed as showing HIV+ive. From a large population of which only 0.1% have HIV, one person is selected at random, given the HIV test, and the pathologist reports "him" // "her" as HIV+ive. What is the probability that the person actually has HIV?
