Non mendelian inheritance

• Mendelian inheritance - the inheritance of traits from parents to offspring through the segregation of chromosomes
• Gregor Mendel - he discovered mendelian inheritance and the laws of heredity first scientist to study traits and dna
• Non mendelian inheritance - genes are not located on a single chromosome, but are distributed throughout the genome
• WW - homozygous dominant

  Ww - heterozygous dominant

  ww - homozygous recessive
• Codominant inheritance - both alleles contribute equally to the expression of a trait
• Dominant - traits that are recessive
• Recessive - A trait that is expressed only when the allele is present in the genotype traits that you have but doesn't show
• Phenotype - the physical expression of a gene.
• Genotype - the genetic makeup of an organism, including the alleles it carries
• Heterozygous - having different alleles at one locus on a pair of chromosomes
• Homozygous dominant - when both alleles are dominant, the phenotype is expressed
• Heterozygous dominant - when both alleles are dominant, the phenotype is expressed
• Homozygous recessive - when both alleles are recessive, the phenotype is expressed
• Punnet square - A diagram used to show the probability of offspring from a cross
