Law of Segregation vs. Law of Independent Assortment By: BD Editors Last Updated: April 24, 2019 The Austrian monk Gregor Mendel conducted revolutionary experiments with pea plants in the early 1800s showing the existence of traits (he called them “factors”) that offspring inherit from their parents. His work culminates in the three principles of Mendelian inheritance; the law of segregation, the law of independent assortment, and the law of dominance. The law of dominance says dominant alleles (a variation of a gene) are always expressed in the phenotype (appearance) of an organism because they mask the effects of recessive alleles....

The sequel to Star Wars Jedi: Fallen Order once again features Cal Kestis as the protagonist, so it makes sense then that he’d be the one immortalized in the new figures alongside his droid companion BD-1....
