To help you understand the difference between dominant and recessive genes, the experts of Vedantu 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. Here you will find the ideal summary of the difference between dominant and recessive genes. The subject experts at Vedantu have simplified the concept in an easy to understand manner so that you can understand the concept easily. You can refer to it as per your convenience. You can either download the study material on this topic or study it online. This will make your preparation easier. In fact, you can use it to revise the chapter quickly. The sorted points will help you remember the entire concept within a short period of time. You can rest assured that this difference has been framed by the expert biology teachers at Vedantu. Why should you refer to the study material on Dominant and Recessive Genes differences on Vedantu?The prime reason for referring to Vedantu’s study material to understand the basic biology concepts is organization. The experts are well experienced in understanding where the students generally face doubts while studying a new concept. By using this experience, our subject experts prepared the right notes for addressing the doubts of students and to make the concepts easier to understand. If you consider the topic of difference between dominant and recessive genes, you will find that the textbook content might not be enough to understand the concept. The teachers at Vedantu walk the extra mile to find the best way to make the topic easily comprehensive for all students. The difference between dominant and recessive genes is an interesting topic of genetics that has immense application in real life. By referring to the dominant trait and recessive trait notes on Vedantu, students will be able to answer various questions from this topic in the exam. The terminologies of this concept have been simplified in these notes for a better understanding of students. Want to read offline? download full PDF here Download full PDF Is this page helpful?

ANSWER: Dominant is always expressed when present. Recessive is only expressed when no dominant genes are present.
What is an example of a dominant gene?Dominant alleles show their effect even if the individual only has one copy of the allele (also known as being heterozygous?). For example, the allele for brown eyes is dominant, therefore you only need one copy of the 'brown eye' allele to have brown eyes (although, with two copies you will still have brown eyes).
What is an example of a recessive gene?Examples of Recessive Traits
For example, having a straight hairline is recessive, while having a widow's peak (a V-shaped hairline near the forehead) is dominant. Cleft chin, dimples, and freckles are similar examples; individuals with recessive alleles for a cleft chin, dimples, or freckles do not have these traits.
What is meant by dominant genes and recessive genes give one example of each?The gene which can decide the appearance of an organism only in the presence of another identical gene is called a recessive gene. For example, in pea plants, the dominant gene for tallness is T and the recessive gene for dwarfism is t. (c) Genes are responsible for the characteristic features of an organism.
