They're near the tips of the chromosomes and that pea plant chromosomes cross over frequently.
Crossing over is when a gene "jumps" from one chromosome to another. This happens during meiosis (when the pea plant is making sex cells). Two genes are much more likely to swap places if they are very close to the tips of their chromosomes; the middle of the "X" is very stable.

You can assume that they are fairly far apart on that chromosome, allowing a greater frequency of crossing over.
