The question is incomplete. The complete question is:

A recent study compared the Homo sapiensgenome with that of Neanderthals. The results of the study indicated that there was a mixing of the two genomes at some period in evolutionary history. What data were discovered that suggested this conclusion

A) some Neanderthal sequences not found in living humans

B) a few modern H. sapiens with some Neanderthal sequences

C) duplications of several Neanderthal genes on a Neanderthal chromosome

D) some Neanderthal chromosomes that are shorter than their counterparts in living humans

Answer:

B) a few modern H. sapiens with some Neanderthal sequences

Explanation:

The mixing of genomes of two species generally results in shared sequences and some common genetic traits in the descendants of these species. Mixing of genomes of <em>Homo sapiens</em> and Neanderthals would have resulted in the presence of some common gene sequences in their genomes. If the conclusion that the mixing of genomes of these two species has occurred is correct, some of the modern <em>Homo sapiens </em>should have the genome sequences that were otherwise present in the genomes of Neanderthals only but not in that of the <em>Homo sapiens</em>.

<h3>What is West Nile Virus?</h3>

In the continental United States, West Nile virus (WNV) is the primary culprit of mosquito-borne illness.

It is most usually transmitted to humans by the bite of an infected mosquito. WNV cases occurs in seasons of mosquito, which begins in the summer and lasts into the fall.
