Blood Types Probability

Punnett Square Phenotype : This is the "outward, physical manifestation" of the organism. Genotype : The genotype refers to the entire set of genes in a cell, an organism, or an individual Homozygous refers to having identical alleles for a single trait Heterozygous refers to having two different alleles for a single trait.

Blood Type ( Phenotype) Genotype A AA (homozygous) AO (heterozygous) B BB (homozygous) BO (heterozygous) AB O OO

Punnett Square: Practice Problems A set of parents think their baby was switched at the hospital. The mother is heterozygous A the father has homozygous B and the baby has blood type A. Could these be the baby’s parent?

Blood Probability Problems Blood Type % of population Antigen Percentage A 41 Rh+ 85 B 10 Rh- 15 AB 4 M 30 O 45 N 22 S 48 To determine the probability of a person with a particular combination of blood types, change the percentage to fractions and find their product and then multiply them. What is the probability of someone having AB+, M?

Blood Typing Simulation We will be determining blood types using Anti-A serums, Anti-B serums, and Anti-RH serums. Clumping = + (Positive) No Clumping = - (Negative) Agglutination is clumping together (usually referring to blood cells).
