Great strides in genetics came after which epidemic?

Influenza, in the year 1918

Explanation: The Influenza pandemic 1918, was one of the severe pandemics in the world history. It had a bigger death toll than world war I. About 33% of the world's population was infected and it mostly affected the  people aged between 20 to 40. Spain was the first to report the pandemic as it had free press.

It led to a great stride in genetics as scientists had to find the cause as well as cure to an unknown disease.

your answer is true

i am 100% sure

explanation:

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
