Natrual variations i think
So here we have two heterozygous organisms that will mate. You can put them into a Punnet square, just to be sure of your answers and to find all possible genotypes :
R r
R RR Rr
r Rr rr
So you have RR, Rr and rr as your possible genotypes.

- Also in the soil is able to produce good fungi and bacteria encouraging better root development due to healthy vines resulting to vigorous growth and better fruit.
- Moreover the plants are able to receive special attention and care from the farmer thus enhancing faster growth.
