It’s a pleasant wait for the expecting parents to know whether it’s a girl or a boy who is going to bring joy and happiness into their home. Certain countries abroad declare the sex of the baby but it’s a wrongful act in India. The desire for a male child has decreased tremendously with the present generation and in fact, couples nowadays wish for a girl baby. Our genetic makeup determines many of our physical traits, characteristics and attitude. There have been wild guesses on the sex of the baby depending on weird factors such as the expecting mom’s looks, the position in which the baby kicks mostly and also depending on the signs of morning sickness. Science comes to rescue here declaring that a man’s genetic makeup can play an integral role in determining the sex of the baby. This is logical and comes as a welcome relief to all the myths and stories surrounding the sex of the baby. Apart from determining the sex of the child, a man’s weight can even affect obesity risks in his offspring which has been explained in detail at www.firsteatright.com.
A group of researchers did a family tree study which included 927 family trees containing information on more than 5,50,000 people from North America and Europe going as back as 1600. The study predicts that the man inherits the tendency to produce sons or daughters from his parents. A man is likelier to have a son if he has more brothers but more likely to produce a daughter if he has more sisters. Sadly, the same relationship between sex of the siblings and sex of the offspring was not found in the case of women. Male to female ratio remains fairly balanced which means that on the whole, men deliver an equal amount of ‘X’ or ‘Y’ chromosome, but it is the shift in balance in certain couples that favors only boys or girls.
Women only pass the ‘X’ chromosome always and it is men who pass either the ‘X’ or ‘Y’ chromosome determining the sex of the fetus as a girl or boy respectively. An X chromosome from mom and another X chromosome from dad make a baby girl (XX) while an X chromosome from mom and a Y chromosome from dad make a baby boy (XY). It is the number of men with the X chromosome to the number of men with the Y chromosome who affect the sex ratio of children born every year.
There have been various theories put forward such as the difference in time in the woman’s monthly cycle to the period until which sperms wait in the testicle which determines the ‘X’ or ‘Y’ chromosome produced by the father. The study shows that every gene consists of two parts called as alleles and each of the allele is inherited from either parent. Men are likelier to carry two different types of alleles that pave way for three different combinations in a gene that control ratio of the X and Y sperms:
World War Witnessed the Birth of Boys
There was an increase in the number of boys born every year in most countries around the world after the World War. The explanation that researchers give for this is that men who fathered more sons were likelier to see a son return from the war and the son was likelier to bear a male offspring due to his genetic inheritance from his father. Men who fathered more girls would have lost their only son in the war and those sons would have fathered a female offspring. This explains why men who survived fathered more male children resulting in a greater number of boys compared to girls in the after-war period.
When there are more males in a generation the females are likelier to find a mate easily. Men who have more daughters will pass on their genes causing more females to be born in later generations.
Male or female, it is required that we nurture a child with all the talents, capabilities and potential bringing out the best in our daughter or son.
