FAQs on Monohybrid Cross Video Lecture - NEET

1. What is a monohybrid cross?
Ans. A monohybrid cross is a breeding experiment that involves the study of the inheritance of a single trait between two individuals. It is performed to understand how a particular trait is passed from one generation to the next.
2. How is a monohybrid cross performed?
Ans. To perform a monohybrid cross, two individuals with contrasting traits for a specific characteristic are bred. The offspring produced from this cross are then observed to determine the pattern of inheritance of the trait in question.
3. What are the possible outcomes of a monohybrid cross?
Ans. The possible outcomes of a monohybrid cross depend on the type of inheritance involved. If the trait follows Mendelian inheritance, the offspring will exhibit either dominant or recessive phenotype in a 3:1 ratio. However, if the trait is influenced by incomplete dominance or codominance, the offspring may display intermediate or blended phenotypes.
4. What is the purpose of performing a monohybrid cross?
Ans. The purpose of performing a monohybrid cross is to study the inheritance pattern of a specific trait and understand the principles of heredity. It helps in determining whether the trait is recessive or dominant, and provides insights into the underlying genetic mechanisms.
5. How does a monohybrid cross contribute to the field of genetics?
Ans. Monohybrid crosses are fundamental experiments in genetics that contribute to our understanding of gene transmission and inheritance patterns. They help in unraveling the basic principles of genetics and provide a foundation for more complex genetic studies, such as dihybrid crosses and pedigree analysis. By studying monohybrid crosses, scientists can make predictions about the inheritance of traits and develop strategies for selective breeding in agriculture and animal breeding.
