Biology X | CHAPTER – 9 Heredity and Evolution | ACCUMULATION OF VARIATION DURING REPRODUCTION
CHAPTER – 9 Heredity and Evolution 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…

Biology X | How do Organisms Reproduce | Reproduction in Human Beings
Reproduction in Human Beings So far, we have been discussing the variety of modes that different species use for reproduction. Let us now look at the species that we are most interested in, namely, humans. Humans use a sexual mode of reproduction. How does this process work? Let us begin at an apparently unrelated point.…
