FAQs on Like Father Like Daughter Class 5 EVS Chapter 21 CBSE Notes - 2025-26
1. What is a quick summary of the Class 5 EVS chapter, 'Like Father, Like Daughter'?
This chapter provides a summary of heredity, explaining why children often resemble their parents or other family members. It explores how certain physical traits, like eye colour, nose shape, or a specific laugh, are passed down through generations. The chapter also clarifies that not all conditions are inherited, using polio as an example of a disease caused by a virus, not genetics. This helps students quickly revise the difference between inherited traits and acquired characteristics.
2. What is the main concept to revise in 'Like Father, Like Daughter'?
The main concept for a quick revision is heredity. Heredity is the process by which physical and some other traits are passed from parents to their children through genes. This is the key term that explains why you might have your mother's eyes or your father's smile, forming a core part of your family's identity.
3. How can I summarise the idea that children are similar but not identical to their parents?
For a quick recap, remember that a child inherits a mixture of traits from both parents. You do not get all your traits from just one parent. This is why you might look a little like your mother and a little like your father, or even a grandparent, but you are still a unique individual with your own combination of features.
4. If traits are inherited, does that mean diseases like polio are also passed down from parents?
No, this is a key concept to understand. While physical traits like height and eye colour are inherited, diseases like polio are not. Polio is caused by a virus and is contracted from the environment; it is not passed down through genes from parents. The chapter helps differentiate between traits you are born with (heredity) and conditions or skills you acquire after birth.
5. The chapter summary mentions pea plants. Why is this important for understanding family traits?
The mention of pea plants is a simple introduction to the work of Gregor Mendel, a scientist who is known as the father of genetics. He studied how traits were passed down in pea plants to understand the basic rules of heredity. His work provides the scientific reason why certain family resemblances appear consistently across generations.
6. What is the key difference between an inherited trait and a learned skill to remember from this chapter?
An inherited trait is a characteristic you are born with, passed down from your family through genes, such as your hair texture or the shape of your ears. In contrast, a learned skill is something you develop through practice and effort after birth, like learning to ride a bicycle, reading, or playing an instrument. You inherit traits, but you learn skills.
7. What are some key examples of traits that can be passed down in a family?
For a quick revision, here are some common examples of inherited traits discussed in the chapter:
The colour of your eyes and hair.
The shape of your nose, ears, and chin.
Specific features like dimples or a particular way of laughing.
Your natural height and body build.
8. How is it possible for a child to look more like their uncle or grandparent than their own parents?
This can happen because you inherit a complex mix of genes from your entire family tree, not just your direct parents. A trait from a grandparent might not have been visible in your parent but could be passed on to you. This concept explains why family resemblances can sometimes skip a generation, and you might share a specific feature, like curly hair or a distinctive smile, with an uncle, aunt, or grandparent.
