Genotype is defined as the genetic makeup of an individual, ie the set of all genes in that organism. The gene, in turn, can be defined as a specific nucleotide sequence of DNA that stores hereditary information. They present information that will be responsible for a given characteristic.
Each individual has a specific genotype that is made up of genes from their parents that will be kept for the life of the organism. This information is important to differentiate genotype from phenotype, because, while the genotype is not changed, the phenotype may undergo several modifications during the development of the organism.
THE blood group AB is called the universal receiver because any other blood group can be compatible with this blood group this is due to the absence of anti-bodies in this type
while blood group O is called the universal donor because it is compatible with all blood groups due to the absence of antigen (A and B)
while blood group A receives blood from itself and O and donates blood to itself and AB thesamethinggoeswithbloodgroupB
If a scientist makes the argument that she has found DNA evidence that shows that evolution does not exist, the evidence would be the weak physical similarities among closely related organism and also among distantly related.
