Mom son bache kaise le sakte hai
Aane Wale generation ka to genetics bigad jaega Aise
Agar mother has healthy genes and she is not carrier of bad genes also, her children with her son will be healthy.The explanation is given belowMom son bache kaise le sakte hai
Aane Wale generation ka to genetics bigad jaega Aise
1no gene consists of 2 alleles( one from each parent).An Individual gene consists of a pair.
When both the alleles are bad(recessive)
Then the child is abnormal.
If only one allele is bad....then the child would be a carrier, but normal (issiliye ki the other allele which is good would supress the bad one.Hete the risk is 12%
Isska karan yeh hai ki there is 50% chance that the mother would already haven't transferred the bad allele to her son.When the mother and son have a child together, there is a chance that the son would transfer one bad allele(you may say half a gene) to the child . Again his mother might also provide a bad allele to her child/grand child. child.Then a pair of bad alleles come together in the child/grand child to form a complete bad gene and the child becomes abnormal.
Now why the risk is 12.5%only. There is also chance that the mother might trasmit the good allele instead of the bad one. Similarly the son may also tranfer the good gene. It may so happen that the son might not get the bad(recessive) allele from her mother,instead may have gotten the good allele also.In that case there is no chance that he would tranfer the bad allele to his child.
Lekin if the mother is abnormal herself(instead of being a carrier)which means her entire gene is corrupt (both the alleles are bad or recessive)
Then her child/grand child will have 50% chance of being abnormal !
So genetically abnormal children aren't born out of nowhere. If the parents have bad genes, then only it happens.
That's why a mother son couple from India,Andhra Pradesh......
(they first went to Australia where the son studied medicine and the mother nursing......now both settled in Kobe,Japan with citizenship) had two healthy children and aother underway (against the wishes of the son) when I last chatted with her back in July, 2018.
BTW,the son was a doctor and the mother was a nurse in the same hospital.
The mother had become a widow at a very young age and was leading a miserable life due to traditions.
Jab Bhagwan ko yeh sab manzoor hai toh hum kaun hote hain complain karnebale !
unki maa aur behen ne unhe maaf kar diye the baad me; but her father never approved of their relationship and didn't speak to them even after seven years of their marriage. May be they all have reconciled by now......who knows !
