The answer is clay, if you look it up it will tell you!
1) As blood groups A and B are equally dominant so the individual will express both characteristics in the phenotype.
Notice how in all the 3 other examples the organism is only expensive 1 version (allele) of each gene. For example the mouse with brown fur may have 2 brown fur alleles (and so would have to express this characteristic even if it was recessive) but it could have 1 allele which is less dominant than the brown, in which case brown would be expressed. In this case the alleles were not co-dominant.
Answer: Our kidneys filter out excess ions from our blood so that they can be excreted through urine. If the concentration of ions is too high, the kidneys make sure to filter as much of them as they can out of the body. If there are not enough ions, the kidneys will filter them back into the system.
Hope it helps
