Segregation. The Principle of Segregation describes how pairs of gene variants are separated into reproductive cells. <span>The segregation of gene variants, called alleles, and their corresponding traits was first observed by Gregor Mendel in 1865. Mendel was studying genetics by performing mating crosses in pea plants. He crossed two heterozygous pea plants, which means that each plant had two different alleles at a particular genetic position. He discovered that the traits in the offspring of his crosses did not always match the traits in the parental plants. This meant that the pair of alleles encoding the traits in each parental plant had separated or segregated from one another during the formation of the reproductive cells. From his data, Mendel formulated the Principle of Segregation. We now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.</span>

Yakvenalex [24]

Answer:

Sexual reproduction

Explanation:

In asexual reproduction, the same genes are transferred to the next generation because there is no combination of genes takes place so the rate of variation is very less in asexual reproduction and in sexual reproduction combination of different genes from two different parents occurs which give rise to genetic variation.

So when the plant is put in an environment where harmful bacteria are present then it will prefer sexual reproduction to bring variation in its genome so that it can get the ability to fight against these pathogenic bacteria.  

The plants that reproduced asexually will be eradicated by pathogens because they can not get the new genes to fight against the pathogen due to lack of appropriate variation in their gene.
