Question
Does the 1qh+ polymorphism of the female chromosome affect pregnancy?
Answer
The 1qh+ polymorphism is a type of chromosomal polymorphism on chromosome 1, which is usually not a major issue and does not lead to infertility. However, it may increase the difficulty of pregnancy or the risk of miscarriage. If the next generation’s chromosomes are normal, there is no need to worry. But if there are larger abnormalities in the process of cell differentiation, it may lead to miscarriage.
