Genetic Transmission occurs when chromosomes from parents are combined and passed on to children. Every child is made up of combined chromosomes wherein half of it comes from the father and half of it comes from the mother. This process is one way of determining why children possess certain traits and attributes that resembles both his/her father and mother. Human beings along with other complex life forms transmit their genes to subsequent generations.
Gene transmission means genetic information is passed on only through the reproductive process. The DNA found in cells of human beings is responsible for encoding proteins that are vital for reproduction, growth and survival. DNA has characteristics that are unique along with its structure. It ensures that certain traits can be inherited from parents and even from distant ancestors. This includes height, facial features, skin complexion and many more.
Aside from traits and attributes, genetic transmission is also responsible for determining the cause of illnesses or diseases acquired by children. Aside from physical and mental traits acquired from parents, health is also affected by the said process. Generally, everyone has 23 pair of chromosomes and there are genes present on each chromosomes. A defective genes can caused a particular disorder which is really similar from one or both parents. The risk of transmitting defective genes can be detected as early as pregnancy of the mother.
From the 23 pairs of chromosomes which is present in the nucleus of everybody, each half part of a chromosome comes from the father and the other half from the father. Both men and women are consist of 22 pairs of chromosomes. The only difference is the 23rd chromosome which is called the sex chromosome since it is responsible for determining the gender of the child. Since majority of the combined chromosome is a combination that comes from both father and mother, it is very likely for a child to adopt the same traits that his/her mother possessed.
However there are human traits that are directed by a single gene. This makes the child different at some point from his/her parents. Aside from the number of genes that interacts in a complex fashion, there are other factors that mix with genetic influences that develop certain traits on children. The environment and the personal experiences of a child will also shape certain traits like talents, emotions and intelligence.
