Question

How are feminised seeds produced? Is this done through natural means or does it involve genetic engineering?

In: Biology

Answer 1

Female plants, under the right circumstances, can be induced to produce male flowers. If this happens, the pollen produced by these flowers will not contain any male chromosomes, so 100% of the seeds produced with this pollen should have female genetics.

Normally, a male plant will produce pollen with both chromosomes so the resulting seeds could be either sex.
