FAQs on Inheritance of One Gene Video Lecture - Biology Class 12 - NEET

1. What is inheritance of one gene?
Ans. Inheritance of one gene refers to the passing on of a specific gene from one generation to the next. It involves the transmission of genetic information from parent to offspring through the reproductive process.
2. How does inheritance of one gene occur?
Ans. Inheritance of one gene occurs through the process of sexual reproduction. During this process, the genetic material from a male parent (sperm) and a female parent (egg) combines to form a new individual with a unique combination of genes inherited from both parents.
3. Can inheritance of one gene lead to genetic disorders?
Ans. Yes, inheritance of one gene can lead to genetic disorders. If a gene carries a mutation or abnormality, it can be passed on from parent to offspring, increasing the risk of developing a genetic disorder. However, not all inherited genes result in genetic disorders, as it depends on the specific nature and interaction of the gene.
4. What are the different patterns of inheritance for one gene?
Ans. There are several patterns of inheritance for one gene, including dominant inheritance, recessive inheritance, and X-linked inheritance. Dominant inheritance occurs when a single copy of the gene carrying a dominant trait is enough to express that trait. Recessive inheritance requires two copies of the gene carrying a recessive trait to be expressed. X-linked inheritance refers to the inheritance of a gene located on the X chromosome.
5. Can inheritance of one gene be influenced by environmental factors?
Ans. Yes, the inheritance of one gene can be influenced by environmental factors. While genes provide the blueprint for traits, environmental factors such as diet, lifestyle, and exposure to toxins can affect gene expression. This field of study, known as epigenetics, explores how environmental factors can modify gene activity without changing the DNA sequence itself.
