Chapter Summary
--- PAGE 1 --- 1064CH09 CHAPTER 8 Heredity We have seen that reproductive processes give rise to new individuals that are similar, but subtly different. We have discussed how some amount of variation is produced even during asexual reproduction. And the number of successful variations are maximised by the process of sexual reproduction. If we observe a field of sugarcane we find very little variations among the individual plants. But in a number of animals including human beings, which reproduce sexually, quite distinct variations are visible among different individuals. In this chapter, we shall be studying the mechanism by which variations are created and inherited. 8.1 ACCUMULATION OF VARIATION DURING REPRODUCTION Inheritance from the previous generation provides both a common basic body design, and subtle changes in it, for the next generation. Now think…
