        AB bloodtype in humnans
        
        Alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.
      - Both alleles are expressed, creating a new phenotype
        
        Pure- breeding (homozygous) cattle may have a red or a white coat colour
        
        Hybrid Individuals (heterozygotes), which have one allele for red and one for white coat colour, have a roan appearance- both red and white hairs are present
      - (in a punnet square)
        
        A letter is chosen to represent the gene- for example C for colour
        
        The alleles are written as superscripts next to the gene
        
        As both alleles are expressed, each allele is given a capital letter
        
        Therefore red would be CR and white would be CW and the roan cow would be CR CW
- - - - The allele for red flowers is incompletely dominant over the allele for white flowers. Red + white = pink.
