Selfed plants

WebFeb 13, 2024 · Your plant has various traits, which we will get into later in the article, but these traits include qualities like potency, color, size, growth cycle duration, aroma, flavor, etc. These traits depend on the genes of the plant, which always come in pairs. The plant material came from a previous experiment in which 11 heterozygous maize landraces were self-fertilized to create homozygous lines30. For each landrace, the experiment began with a single, outcrossed parent of unknown genotype, and selfing was continued for at least six generations by single-seed descent. … See more We predicted that purging would lead to GS loss, which was true for 3 of the 11 lines. We also predicted that loss would be dominated by TEs, but TEs are not the only potential genomic … See more TEs and knobs contribute to GS variation, but which among the five components varied over time and contributed to GS change? To address … See more We now turn to a second prediction about purging: over time, there should be a bias against the retention of deleterious SNP variants.
