Genetics affects many aspects of our lives. Identify three ways genetics affects your life or the life of a family member or friend. The effects can be regularly encountered or can be one time only or occasional.
To review:
Three major affects of genetics on our lives or the lives of a family member or friend. Whether these genetic effects are encountered regularly or occur once or occasional.
Introduction:
Genetics is the branch of biology that is concerned with the study of heredity, genes and genetic variation in organisms. Mechanism of trait inheritance and molecular inheritance of genes are considered as the primary principles of genetics in 21st century. The study of gene structure, function, variation and distribution plays a vital role in everyday life of human beings. Genetics in combination with organism’s environment influence the development and behaviour of the organism.
Explanation of Solution
The genetic information present in DNA is organised in a large number of specific coded instructions called as genes. This genetic information, affects our day to day life by a number of ways. The physical appearance of the people such as the eye colour, texture of the hair and many other features depends upon the genetic structure of the organism. Genetics also determine the pattern of some diseases and conditions that run in the families. Thus it can help in understanding the risk of passing the disease on to their children by knowing the family history or pedigree of the disease. Health care professionals uses genetics for the identification of certain conditions in the babies before they born, by using techniques such as prenatal testing. The studies based on human families have indicated that overall variation in adult lifespan (approximately 20-30%) is accounted by genetic factors.
The type of genetic effect will determine whether it will encounter regularly or occur one time or occasionally. For example, the physical appearance of a person is a type of genetic effect that encountered regularly whiles the occurrence of genetic disease seen occasionally.
Thus it is concluded that physical appearance of a person, pattern of some specific diseases and the overall variation in adult lifespan are the three major genetic affects of our lives or the lives of a family member or friend.
