Introduction
The human blood group system is determined by genes, and the Rh blood group system is no exception. The Rh blood type is controlled by a pair of alleles, namely the Rh positive gene and the Rh negative gene. When a person's genetic combination is DD or Dd, their blood type manifests as Rh positive; whereas when the genetic combination is dd, it results in Rh negative blood type, also known as "panda blood."
Generally speaking, "panda blood" refers to Rh-negative blood type. Rh-negative blood type is hereditary, but it follows a recessive inheritance pattern, and the probability of inheritance is relatively low. The specific analysis is as follows:
The inheritance pattern of Rh-negative blood type follows Mendelian genetics, but Rh-negative is a recessive trait. If one parent has Rh-positive blood type and the other has Rh-negative blood type, their children may not necessarily inherit the Rh-negative blood type; that is, it may not definitely be passed on to the child, although the probability of the child having Rh-negative blood type is relatively high. If both parents are Rh-negative, the trait will almost certainly be passed on to their children, resulting in offspring with Rh-negative blood.
In addition, the inheritance of Rh-negative blood type may also be influenced by grandparents or even earlier generations. If Rh-negative genes exist in their genetic makeup, these genes may be passed down through the hereditary line to future generations.
For families concerned about the inheritance of Rh-negative blood type, it is recommended to perform blood testing on the newborn after birth to determine the infant's blood type.
