If by heterozygous you mean someone has one allele for A (AA or Aa) type blood and one for O (ii), though a third allele, for type B, is also a possibility.
If the parents are AA X Ai (phenotype would be A for both) then possibilities for the offspring are: Ai and AA, and all will be type A.
If it's AA (A Blood) x AB (AB blood), then their children will be either AA or AB.
A Punnett square is a diagram used to predict the possible genotypes of offspring in a genetic cross. It displays all possible combinations of alleles that parents can pass on to their offspring.
You dad can either be O, AB, A,or B and he can be positive or negative.
To fill out a Punnett square for a genotype like RrYY, you would list the possible alleles for each parent horizontally (Rr for one parent, and YY for the other) and vertically. Then, combine the alleles to fill in the squares (RY, Ry, rY, ry) to show the possible genotypes of offspring resulting from this cross.
The price of a punnet of eggs can vary depending on the location and quality of the eggs. On average, a punnet of eggs typically costs between $2 to $5.
As per a Punnet Square: Aa crossed with aa can result in Aa, Aa, aa, or aa. So 50% heterozygotes, 50% recessives.
A punnet square is a diagram showing the gene combination that might result from a genetic cross and it can be bigger than 2x2A diagram that is used to predict an outcome of a particular cross or breeding experiment is called punnet square.

The American Red Cross website is a great reference for blood types. The American Red Cross can give you very detailed information on all blood types.
It can also be called a genetic cross
it is a diagram showing the probabilities of the possible outcomes of a genetic cross
From my research I haven't found a way to know for certain your baby's blood type before birth. You can however narrow it down some if you know the father's and your blood types you could make a punnet square.
All blood types are usually taken by the American Red Cross. It is possible that they have an excess of certian types, and are looking for the others.

The American Red Cross website offers a lot of information on blood types. You can find charts on recipient-donor compatibility, blood types by population, and how blood type is determined. You can find this information at http://www.redcrossblood.org/learn-about-blood/blood-types
Punnett squares are used to predict the possible blood types of offspring in a genetic cross involving parents with different blood types by showing all the possible combinations of alleles that the parents can pass on to their offspring. This helps determine the likelihood of each blood type in the offspring based on the parents' genotypes.
Your friend is correct. There are actually 8 different blood types all together. The best way for you to obtain a list and more information about all the blood types, would be to contact the American Red Cross.
