Segregation


Definition:

  • (n.) The act of segregating, or the state of being segregated; separation from others; a parting.
  • (n.) Separation from a mass, and gathering about centers or into cavities at hand through cohesive attraction or the crystallizing process.

Example Sentences:

  • (2) Both types of oral cleft, cleft palate (CP) and cleft lip with or without CP (CLP), segregate in these families together with lower lip pits or fistulae in an autosomal dominant mode with high penetrance estimated to be K = .89 and .99 by different methods.
  • (3) Reciprocal translocations involving the short arm of acrocentric chromosomes can segregate to produce partial duplications without associated deletions.

  • (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.
