They will have different traits.
If two brothers inherit different sets of alleles from their parents, they will have different phenotypes. For example, one may have blue eyes and the other may have brown eyes. One may be tall and the other may be average height. One may have type A positive blood type and the other may have type A negative blood type. Regardless, they can only inherit the alleles that their parents carry in their own genomes.
From their parents.
the alleles from the parents
Organisms inherit their alleles from their parents. In sexual reproduction, the alleles are usually inherited from two parents. In asexual reproduction, the alleles are inherited from a single cell and are genetically identical to the parent.
The answer is genotype
The brothers have different alleles. They received different alleles from their parents

the alleles from the parents
The alleles for a given trait are inherited from an individual's parents.
the spinone puppy must inherit its parents alleles
Offspring inherit their alleles from their parents.

NO. The alleles that lead to "O-type" blood are recessive to the alleles that lead to "A-type" blood and the child would have to inherit this "A" from one of his/her parents. Given that both parents are "O", there is nobody to inherit the "A" from. (This issue also presents with the exclusive RH- in the parents and RH+ in the child, because RH+ is dominant over the recessive RH-.)
you need two parents to get it but one parent to become a carrier. You need two parents with one of the alleles to inherit it but if you have one parent with the allele you might be a carrier. If you have two parents with the allele it does not mean that you will definitely have it. This is because the allele for cystic fibrosis is recessive.
You need to inherit the same recessive allele from both parents. Which in turn means, that both parents need to have each have at least one copy of said recessive allele.
