Understanding ABO Blood Groups
The ABO blood group system is determined by three alleles: A, B, and O. Our blood type punnett square calculator helps you understand how these alleles combine to create different blood types in offspring.
ABO Allele Combinations:
- Type A: AA or AO genotypes
- Type B: BB or BO genotypes
- Type AB: AB genotype (codominance)
- Type O: OO genotype (recessive)
Both A and B alleles are codominant, meaning they can both be expressed when present together, resulting in AB blood type. The O allele is recessive to both A and B alleles.
Rh Factor Genetics
The Rh factor is determined by another gene with two alleles: positive (+) and negative (-). Our abo punnett square calculator combines both ABO and Rh inheritance patterns.
Rh Inheritance:
- Rh Positive (++): Homozygous dominant
- Rh Positive (+/-): Heterozygous
- Rh Negative (-/-): Homozygous recessive
The positive allele is dominant over the negative allele, so individuals with at least one + allele will have Rh positive blood type.
Medical Applications of Blood Type Genetics
Blood Transfusions
Understanding blood type compatibility is crucial for safe blood transfusions and medical procedures.
Pregnancy Planning
Blood type genetics help predict potential Rh incompatibility issues during pregnancy.
Genetic Counseling
Healthcare professionals use blood type calculators to assess genetic risks and compatibility.
