Why is genetics important?
Genetics helps to explain: What makes you unique, or one of a kind. Why family members look alike. Why some diseases like diabetes or cancer run in families.
-
What are branches of genetics?
To understand the field of Human Genetics in to, we need to expose to various overlapping fields in human genetics like classical genetics, population genetics, cytogenetics, behavioral genetics, molecular genetics, biochemical genetics and Epigenetics.

What is a gene example?
Our genes carry information that gets passed from one generation to the next. For example, genes are why one child has blonde hair like their mother, while their sibling has brown hair like their father. Genes also determine why some illnesses run in families and whether babies will be male or female

Where is DNA stored?
Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

What is the difference between DNA and a gene?
DNA, genes and chromosomes work together to make you who you are. Chromosomes carry DNA in cells. DNA is responsible for building and maintaining your human structure. Genes are segments of your DNA, which give you physical characteristics that make you unique.

Why is DNA called a gene?
To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies. Each DNA sequence that contains instructions to make a protein is known as a gene.

How is genetics defined?
Genetics is the study of how genes and how traits are passed down from one generation to the next. Our genes carry information that affects our health, our appearance, and even our personality!

Why is it called genetics?
The word genetic comes from the Greek word genetikos, which comes from the word genesis meaning “origin“. Its use as an adjective has evolved from meaning “pertaining to origins” in 1831 to “resulting from common origin” in 1859 and finally “pertaining to genetics or genes” in 1908 [8]

What are the basics of genetics?
Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than one percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases.

Why study genetics?
Genetics occupies a central position in modern biology, so its understanding is essential for all scholars of the life sciences. The discipline has great impact on many everyday aspects of human life. The food we eat and the clothes we wear come from organisms improved by application of genetic principles.
