Patient's question:
Hello doctor, why is it said that if one partner in a couple has chromosomal abnormalities, it can also lead to fetal demise. But if the man has chromosomal abnormalities, why didn't this person stop developing in the womb during fetal development and come out very healthy? Why wouldn't his chromosomal abnormalities cause fetal demise, but his fetus would? Doesn't this seem a bit contradictory?Doctor's answer:
Analysis of the condition: Chromosome inheritance is very fascinating... Chromosome inheritance is divided into recessive inheritance and dominant inheritance.Guidance: For example, if the father has recessive inheritance, let's say A represents double eyelids and a represents single eyelids. Then, in your generation, your genes might be Aa, so you have double eyelids. Your next generation might inherit both a from each parent, resulting in aa, which also appears as double eyelids... So this issue is quite complex, and the phenomenon you mentioned is also a normal genetic occurrence.
