Webb28 dec. 2024 · Simple (or Mendelian) inheritance refers to the inheritance of traits controlled by a single gene with two alleles, one of which may be completely dominant to the other. The pattern of inheritance of simple traits depends on whether the traits are controlled by genes on autosomes or by genes on sex chromosomes. WebbResearchers have identified more than 5,000 genetically inherited human diseases and abnormalities. As we learn more about the inheritance patterns for these traits, it is becoming clear that at least some of the twelve exceptions to the simple Mendelian rules of inheritance described here are, in fact, relatively common. cherith baptist church

WebbMendelian inheritance refers to an inheritance pattern that follows the laws of segregation and independent assortment in which a gene inherited from either parent segregates into gametes at an equal frequency.
