What is cystic fibrosis in children from?

A doctor has provided 1 answer

Recessive gene: A mutation is carried in the dna of both unaffected parents & that matching or similar mutation is paired up at conception when the sperm & egg form completed chromasomes with the defective info. Late in pregnancy and after delivery, the effect of the CF gene abnormality begins to reveal itself. In carriers, the good gene compensates for the bad & no problems occur.
