Patient's question:
I got married last year. Recently, I've been experiencing lower abdominal pain, especially around my period. I'm very worried it might affect fertility, and I'm also extremely sensitive to cold and coldness. Can two people with double eyelids have a child with single eyelids?Doctor's answer:
Yes, but the probability is uncertain. Unibrow is a recessive gene (b), while double eyelid is a dominant gene (B). A person's genes exist in pairs, and if there is a dominant gene, the dominant trait (double eyelid) will be expressed, such as BB or Bb. Only bb can express the recessive trait (unibrow). Therefore, if both parents' genes are Bb, they may have a child with unibrow, with a probability of 25%. However, if one parent's gene is BB, it is impossible to have a child with unibrow. But due to the influence of the living environment, the eyelid may not always be completely controlled by genes, so the above analysis is only from a theoretical perspective.
