Viruses are even smaller than bacteria and require living hosts — such as people, plants or animals — to multiply. Otherwise, they can't survive. When a virus enters your body, it invades some of your cells and takes over the cell machinery, redirecting it to produce the virus.

Answer:
The conclusion that cuckolder are able to discriminate kin from non kin
Explanation:
From the above question, researchers carried out tests on the two types of fish (males cuckolder and parental males) to see if they can identify kin and non kin from the offsprings, using a null test.
But the test for cuckolder was rejected by the researchers for the cuckolder so they can't say cuckolder can indentify between kins and non kins, they didn't pass the test so it should be concluded that cuckolder can't identify between kin and non kin, instead of concluding they can identify them, that is the wrong conclusion.
