Yes a male can be cloned and kept as a father plant.
Reveging can be tricky, and does not always work, I just lost 6 plants trying to reveg,,, I worked them to hard, think 50% amber. I learned and will correct my mistake, mothers being created!
Ok the offspring of plant x and plant y lets call z, z would have varying traits. 25% would be 75/25, 50% would be 50/50, and 25% would be 25/75. From here select what to keep as a mother/father or do further breeding with.
