Question
Does chromosomal abnormality affect blood type?
Answer
Chromosomal abnormalities can affect blood type. Human chromosomes are arranged in order of size from 1 to 22, with the largest containing about 250 million base pairs and the smallest about 38 million. The human body has a total of 23 pairs of chromosomes, with the first pair being sex chromosomes, and the second to the 22nd pairs having similar structures and functions. Since women have two different sex chromosomes (XX), their genetic composition is more diverse than men (XY), and chromosomal abnormalities may affect blood type.
