To help you understand the difference between dominant and recessive genes, the experts of have created a summary of dominant and recessive traits. Here, a simple language is used to ensure that every student can understand the concept well and can give correct answers to all the questions from this topic in the exam. From an examination point of view, it is important to learn the difference between dominant and recessive genes appropriately.
Every function our cells perform is controlled by the genetic material inside the nucleus. Every trait we have is decided by the dominant genes. We all know that an offspring gets two sets of genes from the parents. There are two types of genes for the same trait or characteristic. The dominant one is expressed and we can see the same physiological characteristic in an offspring.
What is a Gene? What is the difference between Dominant and Recessive Genes?
Genes are considered to be the blueprints of an organism’s characteristics. It is the genes that decide the kind of biochemical structure and functions the cells will perform. They also decide whether a person will have black hair or blue eyes. It is estimated that humans have 20,000-25,000 genes. The genes can be expressed as information stored in the DNA strands that help a cell to trigger a particular function. Genes can be used for protein synthesis or to trigger any kind of biochemical reaction inside a cell. Not all genes are used to create protein.
As mentioned earlier, every person inherits two different sets of genes for a particular trait. For instance, a person gets a set of two genes related to hair colour from both parents. Only one of them will become prominently observable in the person. It means that one of these two genes will be considered as expressions. The gene that decides the hair colour of that person is called the dominant gene. The other gene that did not get the chance rather is being dominated is called the recessive gene.
Remember that only the dominant trait will be expressed if both dominant and recessive genes are present in the allele. If both the traits are recessive, the recessive trait will be expressed. It might sound confusing to you. If you understand what are dominant and recessive traits and genes responsible behind them, you will start understanding the concept and will be able to answer the questions easily.
