Definition:
(a.) Separate; select.

(v. t.) To separate from others; to set apart.
(v. i.) To separate from a mass, and collect together about centers or along lines of fracture, as in the process of crystallization or solidification.
Example Sentences:
(1) However, the average age at onset of lymphoma varied considerably among the different AKXD strains, suggesting that they have segregated several loci that affect lymphoma susceptibility.

(5) Recombination between markers was observed in matings between phage beta and the heteroimmune corynebacteriophages gamma and L. In such matings between heteroimmune phages the c markers of phages beta and gamma failed to segregate from the imm markers which determine the specificity of lysogenic immunity in these phages.
(6) For analytical purposes, irradiated dogs were segregated into groups according to their clinical status: clinically normal, hypocellular, or with acute non-lymphocytic leukemia.
