Question

what ismendelian and non-mendelian theory

Answer 1

In human majority of normal and pathological features are determined by other genetic mechanisms, which are denoted by the term "non-mendelian genetics." There are many such mechanisms: chromosomal aberrations (Down syndrome), inheritance, sex-linked (blindness), imprinting (Prader-Willi syndrome, Engelmann), the emergence of new mutations (development of cancer), expansion (insertion) repetitive nucleotide sequences (Myotonic Dystrophy ) inheritance of quantitative traits (complex behavioral characteristics).

Chromosome theory of heredity (mendelian theory), one of the generalizations in genetics, claiming that hereditary factors (genes) are located in the chromosomes which transmission from parents to offspring in generations ensures the continuity of the properties and characteristics in individuals of the same species.
