If your husband and you have a positive why baby is o positive?

A baby's blood type is determined by the blood types of both parents. Since you and your husband have positive blood types, it means that each of you has at least one positive allele for the blood type gene. The baby can only inherit a positive blood type if it inherits a positive allele from both you and your husband.

Here's a breakdown of how the blood types are inherited:

* Positive Allele: The positive allele for the blood type gene is dominant over the negative allele. This means that if a person has at least one positive allele, they will have a positive blood type.

* Negative Allele: The negative allele for the blood type gene is recessive. This means that a person must have two negative alleles in order to have a negative blood type.

In your case, both of you have positive blood types, which means that you each have at least one positive allele. This means that it is possible for your baby to inherit two positive alleles from both you and your husband and thus have a positive blood type.
