Lakhmir Singh Solutions Class 10 Biology Chapter 4: Heredity and Evolution

Chapter 4 of the chapter ' Heredity and Evolution' is very interesting as it talks about the evolution of human beings and many other creatures. The continuity of generations because of reproduction has been happening since the beginning of time. However, the evolution of organisms is research still ongoing. In this chapter, the students will learn the very basics of evolution and heredity. The concepts and topics have been incorporated in this chapter very smartly so that the students don't have to get into the depths and get confused but also get a fair idea about it. This chapter has been constructed smoothly that slowly leads into the complexity. A hundred questions cover all the topics and give a brief to the student learning the chapter. The chapter develops a wide range of ideas, and all the topics are covered briefly. The chapter focuses on giving total information on how organisms get their characteristics from their parents and how they have evolved over the years. It covers topics like:

  • Variations
  • Laws of Inheritance
  • Genes controlling characteristics
  • Sex Determination
  • Evolution
  • Darwin's theory of evolution
  • Human evolution

The chapter starts with the section on heredity, and the process of mitosis and meiosis are discussed. Variation, which are the slight differences that ensure the continuity of the species when the conditions are not favourable, is discussed along with the experiments of Gregor Jonan Medel, which led to the three laws of inheritance. The chapter talks about genes and alleles and how they control a characteristic. The chromosomes also play an important role in the gender of the unborn child. The chapter then moves on to the section of evolution, the importance of evolution, evolution of eyes, features and different animals. Next, various theories are discussed, with Darwin's theory being discussed in detail. There are questions in a pictorial format that makes the learning process even more engaging. This chapter is a slight continuation of the previous chapter, 'How Do Organisms Reproduce' and speaks in detail of the subtle confusion seen in the result of that process. The chapter is covered via questions in the solutions PDF provided by the Aakash Institute. There are various kinds of short, very short, long questions with pictures, Multiple Choice Questions, and fill-in-the-blanks.
