If parents next to type O+ and type O- blood have 6 children, what would the children's possible blood types be?

One does not know if the O+ parent is homozygous or heterozygous for the D allele (Rh+).
If the O+ is heterozygous then children will be O negative and or O positive. If they are homozygous for D then they will be adjectives be O+ and all children will be heterozygous for D Rh antigen.
There are only two options, they could be either O+ or O-.
Since O gene is recessive both parents enjoy only O genes to inherit and are thus homozygous for the O gene. All childrens will only inherit O genes and this will be their only group.
Since Rh factor is adjectives by a dominant gene, O- type is homozygous lacking the Rh gene while O+ could be either homozygous or heterozygous for the Rh gene but should have at lowest one copy of the Rh factor gene.
The probabilities depend on the O+ parent, if it's homozygous (both alleles for that gene produce the Rh + factor) then all of the chidren's will be Rh+ since that parent will always inherit this gene and anyone a dominant gene it will always show up, If it's heterozygous (one of the 2 alleles is Rh+ and the other Rh-) then there's 50% chance that the childrens are any O+ or O-.
Lab guy is correct.
Also, my dads O+ and my moms AB.
Yet my 2 brothers and I are A+.
but you guys will be within the O.
