Seedless red apple plants are quite interesting! While most apple varieties naturally have seeds, there are a few approaches to achieving a seedless apple:

1. Genetic Modification: Scientists can alter the genetic makeup of apple trees to produce seedless apples. This method is still experimental and not widely used in commercial production.

2. Grafting and Crossbreeding: Some breeders work on developing seedless apple varieties through grafting or crossbreeding with other fruit varieties. These methods are also not yet mainstream.

3. Sterile Varieties: Some apple varieties are naturally less likely to produce viable seeds due to their genetic makeup. However, true seedless apples are rare.

If you’re looking for apples with fewer seeds or less seed development, you might want to try varieties that naturally produce smaller or fewer seeds.
