A grower produces potato plants from buds on tubers taken from one parent plant. A period of very low temperature damages almost all of the plants.
The grower plans to replace some of the crop with potato plants produced by sexual reproduction.
Which statement explains why this plan could reduce the risk of losing the whole crop during a future period of low temperature?
The offspring have new combinations of alleles, so it is more likely that some plants will survive the cold.
Meiosis changes the base sequences of the alleles, so it is more likely that some plants will survive the cold.
The seeds inherit the cold tolerance their parents developed, so it is more likely that some plants will survive the cold.
Each offspring inherits dominant alleles from both parents, so it is more likely that some plants will survive the cold.
