Inheritance genetics
... Sometimes the alleles of genes always exert their effect – they are neither dominant nor recessive. Instead they are said to be codominant. Examples include flower colour in snapdragon (Antirrhinum), coat colour in short horn cattle, AB blood group and sickle cell trait in humans. We will look at on ...
