In some allele combinations, dominance does not exist.
Using a punnett square - you write the possible gamete combinations of one parent across the top and those of the other down the side.By filling in the square, you determine all the possible allele combinations of the offspring.XRDRdrDrdRDRRDDRRDdRrDDRrDdRdRRDdRRddRrDdRrddrDRrDDRrDdrrDDrrDdrdRrDdRrddrrDdrrdd
Punnet squares show all possible allele combinations resulting from a genetic cross
Yes, it is possible. There are two genetic alleles that together determine whether a person is Rh positive or negative. It is the combination of these alleles within the parents that determine the child's Rh status. In this case, both mother and father are positive so their alleles can only be ++ or +-. The possible combinations are determined by taking one allele from one parent and combining it with an allele of the other until all combinations are made. Positive is the dominant allele so combinations of ++ and +- are considered Rh positive whereas -- combinations are negative. The possible combinations are: ++ which would be an Rh positive baby +- which would be an Rh positive baby -- which would be an Rh negative baby So yes, it is possible.

We can use 36 characters for each of the slots in the combination. Therefore, we have 36^11 possible combinations, or 131,621,703,842,267,136 combinations.
An allele is one of the possible forms of a gene. Most genes have two alleles, a dominant allele and a recessive allele. If an organism is heterozygous for that trait, or possesses one of each allele, then the dominant trait is expressed.DI/Di alleles (ISBT 010) Blood Group Alleles refers to the Diego blood groups and variations on this set of several alleles (approximately 25 of them) can affect the shape of RBCs (red blood cells). Most of the Di has 3 variations Di(a+b-), Di(a-b+) and Di(a-b-). Di(a-b-) is a Null Phenotype which means fails to produce normal gene function.
