Mendel’s law of segregation, as applied to the behavior of chromosomes in meiosis, means that:

#Section 3: Genetics, Cellular and Molecular Biology

  1. pairing of homologs will convert one allele into the other, leading to separation of the types.

  2. alleles of a gene separate from each other when homologs separate in meiosis I, or in meiosis II if there is a single crossover between the gene and the centromere.

  3. genes on the same chromosome will show 50% recombination

  4. alleles of a gene will be linked and passed on together through meiosis
