》Genetics : Definition 

Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in organisms. Gregor Mendel observed that organisms (pea plants) inherit traits by way of discrete “units of inheritance”. This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene.

Types of genetics

There are five types of Genetics

1.) Molecular genetics.
2.) Developmental genetics.
3.) Population genetics.
4.) Quantitative genetics.
5.) Phylogenetics

》Study of Genetics

Genetics is the scientific study of genes and heredity—of how certain qualities or traits are passed from parents to offspring as a result of changes in DNA sequence. All of an organism’s genetic material, including its genes and other elements that control the activity of those genes, is its genome. 

A gene is a segment of DNA that contains instructions for building one or more molecules that help the body work. DNA is shaped like a corkscrew-twisted ladder, called a double helix. The two ladder rails are called backbones, and the rungs are pairs of four building blocks (adenine, thymine, guanine, and cytosine) called bases. The sequences of these bases provide the instructions for building molecules, most of which are proteins. Researchers estimate that humans have about 20,000 genes.

All of an organism’s genetic material, including its genes and other elements that control the activity of those genes, is its genome. An organism’s entire genome is found in nearly all of its cells. In human, plant, and animal cells, the genome is housed in a structure called the nucleus. The human genome is mostly the same in all people with just small variations.


How are genes inherited ?

Our DNA, including all of our genes, is stored in chromosomes, structures where proteins wind up DNA tightly so that it fits in the nucleus. Humans typically have 23 pairs of chromosomes in our cells. The two chromosomes in each pair contain the same genes, but they may have different versions of those genes because we inherit one chromosome in each pair from our mother and the other from our father. Reproductive cells—eggs and sperm—randomly receive one chromosome from each of the 23 sets instead of both so that a fertilized egg will contain the 23 pairs needed for typical development.

How do genes affect health and disease ?

Changes in genes can prevent the gene from doing its job the way it normally would. Some differences in DNA, for example, can lead to incorrectly formed proteins that can’t perform their functions. Also, genetic variations can influence how people respond to certain medicines or a person’s likelihood of developing a disease. Because parents pass their genes on to their children, some diseases tend to cluster in families, similar to other inherited traits. In most cases, multiple genes are involved. Researchers can use DNA sequencing to identify variations in a person’s genome.

1.) Molecular genetics.
2.) Developmental genetics.
3.) Population genetics.
4.) Quantitative genetics.
5.) Phylogenetics.

Is genetics a good career ?

One can pursue genetics as a career by doing courses like Bachelors, Masters & Doctoral degree. Genetics is a wide field and it has applicability in cancer research, assessing newborn defects, Nutrigenomics, DNA sample analysis, etc. The field of genetics allows you to work in medical as well as scientific research.

Is genetics a difficult course ?

Genetics is one of the hardest classes I ever loved. The material is interesting and relevant.

》Is genetics or cell biology  harder ?

Micro was easy. Cell Bio was slightly more difficult due to it being more detail-oriented, and Genetics was by and large a pain in the butt because of the level of detail and reasoning that was demanded of you.
