Single-seed Descent

Marijuana Horticulture

by Jorge Cervantes

A plant is self-fertilized and the resulting seed collected. One of these seeds is selected and grown, again self-fertilized, and seed produced. All progeny and future generations have descended from a single ancestor, as long as n pollen from an external family is introduced. Each generation is the result of selfing one individual from the previous generation.

After six generations of selfing without selection, 98.44% of the genes of an individual are homozygous – this refers to genes, not the number of plants that are homozygous.
