Prior to mendel, most people believed inheritance was due to a blending of parental ‘essences’, much like how mixing blue and yellow paint will produce a green color mendel instead believed that heredity is the result of discrete units of inheritance, and every single unit (or gene) was independent in its actions in an individual’s genome. Extensions to mendelian genetics is needed for expression of the final phenotype Ð9:7 ratio ¥epistasis : one gene can mask the effect of another gene. 4 variations of mendelian phenotypic ratios - alleles can interact with each other in complex ways - incomplete dominance - codominance - pleiotropic alleles. Mendel's laws fail to adequately explain some phenomenon like mitochondrial gene inheritance and inheritance due to linkage between genes on the same chromosome and variation in gene expression and gene interactions can produce results other than phenotypic ratio predicted by mendel's laws. Extensions of mendelian inheritance epistasis and epigenetics remember mendelian ratios true-breeding parents with dominant and recessive traits monohybrid (aa x aa parents) f1 are heterozygous ( aa ) with dominant phenotype f2 are 3:1 dominant to recessive phenotype slideshow.
