Mendelian Traits Non-Mendelian Traits Sex-linked Traits Complete dominance: The dominant (A) trait blocks the recessive (a) if both are present. Mendelian Traits Incomplete dominance: mix like paint. Red (R) x Blue (B)=Purple (RB) Codominance: Like splattering paint. Red (R) x Blue (B)=Red with Blue spots (RB) Non-Mendelian Traits The allele for a trait is only found on either the X or Y chromosome. Usually…the X. Sex-linked Traits

Try These…Please Mendelian Trait-Yellow dominant to green: What are the genotypic and phenotypic ratios for a cross between a heterozygous and homozygous dominant plant? Non-Mendelian Trait-Black and White fur are codominant: What are the genotypic and phenotypic ratios for a cross between a heterozygous cow and homozygous black bull?

3. Non-Mendelian Trait-Red and White flowers exhibit incomplete dominance: What are the genotypic and phenotypic ratios for a cross between a pink flowering plant and a white flowering plant? 4. Hemophilia is sex-linked recessive disorder. List the five possible genotypes and name them. Now cross an affected male with a carrier female and give the genotypic and phenotypic ratios.
