If the process of genetic drift was the cause of this phenomenon, then the resistance allele was also present in the original farm.
<h3>What is genetic drift?</h3>
Genetic drift is a genetic phenomenon that occurs when one allele is fixed in a population due to random chance.
Genetic drift is converse to natural selection, where an allele increases this frequency due to evolutionary constraints.
Genetic drift is well known to be the cause of allele fixation by founder population effects.

The matchup statement associated with rods or cones are:
<h3>Rods:</h3>
- involved with night vision
- smooth plasma membrane surrounding the intramembranous discs
- uses rhodopsin
- used in scotopic vision
- absorption peak occurs at 500 nm
<h3>Cones:</h3>
- highly concentrated in and around the macula
- involved with color vision
- infolded plasma membrane surrounds each disc
- uses photopsin
- absorption peaks occur at 420, 531, and 558 nm
<h3>What are the roles of rods and cones in the eye?</h3>
The Rods are known to help in regards to vision at low light levels or scotopic vision.
The cones are known to help or function in regards to vision at the point of higher light levels or what we call photopic vision.
Hence the matchup above are correct.
