WebFirst of all, determine whether the condition is recessive or dominant. If the trait is dominant, the trait must be one of the parents'. If the phenotype is recessive, because they may be heterozygous, no parent is expected to have the phenotype. Then, determine whether an autosomal or sex-linked (usually X-linked) trait appears on the chart. WebYou can use our blood type Punnett square calculator to calculate the genotype of your offspring. Otherwise, here is how you can calculate your baby’s blood type manually: Write down your blood type and your type’s allele like AA or AO. According to your allele, your child will probably have A-type (75% chance) or O-type (25% chance).
