Heredity
Welcome to our exploration of heredity, where we dive deep into the fascinating world of genetics and inheritance! In this blog, we’ll break down complex questions and provide clear, concise answers to help Class 10 students master the subject. From Mendelian principles to modern genetic understanding, we’ll unravel the mysteries of how traits are passed from one generation to the next. Join us as we tackle questions, solve problems, and build a solid foundation in heredity!

Very short questions
1. Write one function of chromosome.
Ans: Transmission of Genetic Information is the one function of chromosome.
2. Define genetics.
Ans: Genetics is the study of how parential characters are passed down from one generation to the next.
3. What is cell division?
Ans: Cell division is the process by which a single cell splits into two or more daughter cells.
4. Write one difference between Karyokinesis and cytokinesis.
Ans:Karyokinesis is the division of a cell's nucleus, while cytokinesis is the division of the cell's cytoplasm.
5. What is meant by somatic cell?
Ans: Somatic cells are the body's non-reproductive cells that make up tissues and organs.
Or
Somatic cells are any cells in the body that are not involved in reproduction.
6. What is mitosis cell division?
Ans: Mitosis is a type of cell division where a single cell divides to produce two identical daughter cells with the same number of chromosomes as the original cell.
7. Define meiosis cell division.
Ans: Meiosis cell division is the type of cell division where a single cell divides to produce four identical daughter cells with half number of chromosome as the original cell.
8. Write one difference between Mitosis and Meiosis cell division.
Ans: In mitosis cell division number of chromosome equal as the mother cell where in meiosis number of chromosome is half as the original cell.
9. Write one significance of mitosis cell division.
Ans: Mitosis cell division help to replace damaged cell.
10. Why is meiosis cell division important?
Ans: Meiosis cell division is important because it create genetics diversity.
11. Write one significance of the cell division shown below.
Ans: Give figure show meiosis cell division and it one significance is
- genetics diversity in offspring.
12. Write down the full form of DNA.
Ans The full form of DNA is Deoxyribo Nuclic Acid.
13. Write down the function of RNA.
Ans: The function of RNA is Protein Synthesis.
14. Write one difference between somatic chromosome and sex chromosome.
Ans: Somatic chromosomes are non-reproductive chromosomes that make up most of the body’s cells, while sex chromosomes determine an organism’s sex and are involved in sexual reproduction.
15. What is sex determination?
Ans: Sex determination is the process that decides whether an organism will be male or female.
16. Mitosis cell division is called equational cell division, why?
Ans: Mitosis cell division is called equational cell division because the number of daughter chromosome equal as mother cell's chromosome.
17. What is gene?
Ans: A gene is a section of DNA that carries the instructions for making a specific protein or trait.
18. Write one difference between haploid cell and diploid cell.
Ans: A haploid cell has one set of chromosomes, while a diploid cell has two sets of chromosomes.
19. Name the plant selected by Mendel for his experiment.
Ans: Mendel selected pea plant for his experiment.
20. Why is red characteristics called dominant out of red and white flower bearing characteristics?
Ans:Red flower color is called dominant because it shows up even if only one copy of the red character is present.
21. Give one example of selective breeding.
Ans: One example of selective breeding is
Livestock: Cattle, chickens, and pigs are often selectively bred to increase meat or milk production, improve growth rates, or enhance disease resistance.
22. What is cross breeding?
Ans: Cross breeding involves mating different breeds or species to create offspring with mixed character from both parents.
23. How is pomato produced?
Ans: pomato is produced by grafting a tomato plant onto a potato rootstock to grow both tomatoes and potatoes on the same plant.
24. How is liger produced?
Ans: A liger is produced by mating a male lion with a female tiger.
25. Write one difference between dominant and recessive characteristics.
Ans: A dominant characteristic will appear in the offspring if at least one parent carries the dominant allele, while a recessive characteristic requires both parents to carry the recessive allele for it to appear.
