Answer:
The correct answer is option B, that is, less genetic diversity in later generations.
Explanation:
A pandemic that spread across Europe between 1348 and 1350 was named as the Black Death. It has been predicted that of the total population of Europe at that time 30 to 60 percent died due to the pandemic. The geneticists are still trying to document the influence of Black Death on the population of Europe today.
It has been found that in England, the genetic diversity is found much lower in comparison to what it was in the eleventh century, and is primarily due to so many people dying in the 1300s. However, the rest of Europe does not demonstrate a dropped amount of genetic variation, which maybe because of the enhanced patterns of migration in other places.
Answer is: p<span>olymerase chain reaction (PCR).
</span>Polymerase chain reaction<span> (</span>PCR<span>) is a technique used in </span>molecular biology<span> to </span>multiply<span> a one or more copies of a segment of </span>DNA,<span> developing thousands to millions of copies of a particular </span>DNA sequence. PRC was d<span>eveloped in 1983 by </span>Kary Mullis (<span>1944 - ).</span>
