Scientists have retrieved separately fertilized nonidentical embryos of mice at the 64-cell stage and fused them together into one cell-cluster. Instead of developing into two mice, this develops into one mouse with many parents. Such animals from fused zygotes are called chimeras. Recently, a strange case occurred in a European hospital that revealed this could occur naturally in humans. A child with blood type AB was born to a mother with blood type O. Ruling out the possibility of a mixup in parents, the medical researchers examined the mother's parents and found many genetic markers that indicated that the type O mother who gave birth to the type AB child was actually a chimera from naturally fused embryos. One embryo gave rise to her bloodforming tissues and the other developed into her reproductive tissues. Briefly describe, the blood type of the child, the two tissue types existent in the mother, and indicate which contributed to the child, and the necessary blood types of the grandparents
