- Codominance
- Blood group
- 4 potential blood groups O (recessive) A, B & AB (dominant)
- Letter I represents blood group gene, 3 different alleles for blood type gene Iº, I?, I?
- I & I codominant so when individual has both alleles (genotype I I ) they'll have blood type AB as one isn't dominant over the other
- Iº recessive so need 2 of recessive alleles for blood type O to be expressed (genotype IºIº) if you get Iº with e.g. I (genotype I Iº) only see effect of I?, so have blood type A
- Letter I represents blood group gene, 3 different alleles for blood type gene Iº, I?, I?
- Can predict using Punnet sqaures
- 4 potential blood groups O (recessive) A, B & AB (dominant)
- when both alleles are expressed in the phenotype as one doesn't dominate the other
- Both codominant alleles are shown by uppercase letters (e.g. W for white & B for black)
- Can predict using Punnet sqaures
