Heredity and Evolution
Science Solutions from Chapter -1 - Heredity and Evolution
In this chapter, we will learn about evolution, which are the slow and gradual changes taking place within a species over time. It describes the inheritance of those changes from one generation to the next generation.
Practice Other Topics from Heredity and Evolution
We learn in this topic that during reproduction, the traits are transferred from one generation to the next generation. If the mode of reproduction is sexual, variation in traits is accumulated over many generations. It helps in the survival of the organisms in diverse niches.
The transfer of traits from parents to offspring through sexual or asexual reproduction is known as heredity. In this topic, Mendel’s Law of Inheritance explains how these traits will be inherited from parents.
In evolution, the variations occur in the inherited traits for the survival of organisms in diverse niches. These variations occur by natural selection, mutation and genetic recombination that are broadly discussed in this topic.
