Blood Types

The charts below can assist you to determine either: 1. The ABO blood type of the child when the blood type of the father and the mother are known (top chart), or. 2. The ABO blood type of the father if the blood type of the child and the mother are known (bottom chart). ABO Blood Type Calculator. ABO blood types can be complicated to understand. Each biological parent donates one of their two alleles to make up the child’s blood group. So the child’s blood type depends on the alleles that the parents carry. For instance, if the mother has the blood type AO and father has blood type BO, the child can end up with any one of the blood groups: A (25%), B (25%), AB (25%) or O (50%).

The most common of these is the DNA test or a more out-dated, almost totally disused way, is by using a blood type chart or blood- typing, as it is commonly referred to. A man can opt for any one of these two tests although the most accurate results can only be provided with a DNA test. The samples must then be sent to the lab for testing — obviously both the father and the child need to provide samples.

The two samples are compared to see if the alleged father and child share the same genetic markers. In the event that the man is the biological father of the child, the test will usually give a This how to make a dye sensitized solar cell because DNA is the material that is inherited by children from their parents.

It can only be used to disprove parentage and not to prove that an individual is the father of the child. The DNA result is on the other hand very reliable. Unless there was a mistake in the testing process, the result is conclusive evidence of either parentage or non- parentage.

Another difference between determining paternity by DNA and determining paternity by blood type chart is the fact that for the blood type chart to be used, information on the blood how to make a concrete benchtop of either one or both of the supposed parents must be available. In the absence of this information, the chart becomes obsolete. There is also the obvious difference that the DNA test is actually a test that is carried out.

An actual scientific test on the DNA profiles has to be done. When using a blood type chart in a bid to establish parentage, no tests need to be done. This is especially true when the blood group of each supposed parent is known.
