Blood Type: How to Decide & Project Your Child’s Blood Type?
Tarun Gupta asked:
Blood typing is a method of determining a person’s blood type by serological methods. These blood types depend on whether or not there are certain antigens on the red blood cells & if there are antibodies to these substances. By careful planning a couple can decide & project its child’s blood type which is quite important because not all blood groups are compatible with each other & if child & mother are of incompatible blood types, mixing of their blood may lead to blood clumping or agglutination, which may be fatal for both mother & the baby.
Deciding your child’s blood type:
Each biological parent donates one of the two A/B/O alleles to his/her child. Alleles are possible types of a particular gene, in this case the blood type gene. There are three basic blood type alleles: A, B, and O which codes for A, B or none of the RBC surface antigens that decide corresponding blood types respectively. Children have two alleles, one inherited from each parent. The possible combinations of the three alleles are OO, AO, BO, AB, AA, and BB. If the parents don’t know their blood type, there are lots of easy ways to learn the blood type.
Consequently, a person with blood type B may have a B and an O allele, or they may have two B alleles. If both parents are blood type B and both have a B and a recessive O, then their children will either be BB (if each parent passed on the B allele), BO (if one parent passed on B and the other parent passed on O), or OO (if both parents passed on the O allele). If the child is BB or BO, they have blood type B. If the child is OO, they will have blood type O.
Take care of Rh factors too:
Rh Factor is also an antigen the alleles for which are also inherited from our parents, but independently of the ABO blood type alleles. Someone who is Rh positive or “Rh+” has at least one Rh+ allele, but could have two in homozygous state.
Similar to A, B, O & AB blood types, Rhesus factor (Rh +/-) genetics is determined from the possible allele combinations inherited from each parent. The DNA of each parent carries two Rh alleles either positive (+) or negative (-). The positive Rh factor allele is dominant over the negative Rh factor allele meaning that if a parent’s pair of Rh factor alleles are one positive (+) and one negative (-), the positive allele will dominate the negative allele and result in a positive Rh factor (Rh+).

Doing A Hair Test For Paternity
Judy Wellsworth asked:
In order to do a hair test for paternity, you need to have hair that still has the roots and follicles still attached. This means, taking strands from a brush will not work, you need to pull the hair from your head and look to make sure the hair follicles and roots come attached to the sample. In most cases of a paternity test, three to four strands of hair require submitting in order to do the DNA testing.
Hair test for paternity costs less than any other DNA testing and is just as reliable as any other form of testing. Genetic DNA paternity testing allows courts and individuals to confirm paternity of a child and the father or mother. These tests do hold up in court and do provide for accurate results. Most people use a clinical facility, but some receive a home test kit in the mail and send the sample out for testing.
Why do people need a hair test for paternity? In some cases, genetic DNA paternity testing is done to determine the parentage of a child. This procedure allows courts, parents and other concerned individuals to know who the parents are, whether it is for the mother or the father. This information allows the custodial parent to receive support of the said child. In most states, if you receive any kind of support from the government, you need to know the paternity of the father.
Before genetic DNA paternity testing helped to identify a father, men who were said to be a father were just that, determined and appointed the father. Today, a simple paternity test will reveal if the individual is the legal father or not. This procedure has also aided in the overturning of many rulings by the courts when confirming that someone was a father, they have been found not to be the father, which leads to hardship for many.
Earlier tests conducted used the blood type of the mother and father to determine if the baby belonged to the father. A very inconclusive test that throughout the years has caused many problems in the courts as fathers have begun to use the updated hair test for paternity as a way to prove they are not the biological father. Some people feel this could cause a big problem with child support agencies, as they try to collect from the real father after collecting support from the wrong father for years.
With the advancement of DNA testing, the entire process has helped and hindered in many areas as people use the genetic DNA paternity testing to find lost children and find missing fathers. Technology keeps advancing and so does paternity testing.
