Bacteria that can withstand heat have a survival advantage during a heat wave. This advantage is linked to specific variations in their genetic makeup, allowing them to thrive in conditions where other bacteria might struggle or perish. This example highlights ...

Variations in a species do not have equal chances of survival because the environment poses different challenges, and the nature of variations determines the advantages or disadvantages of individuals in coping with these challenges.

Sexual reproduction enhances diversity by combining genetic material from two parents, introducing variations through meiosis and genetic recombination. The rules of inheritance, to be discussed further, will delve into the mechanisms governing how these variations are passed on from one ...

Sexual reproduction introduces greater diversity compared to asexual reproduction. The combination of genetic material from two parents, along with processes like crossing over and independent assortment during meiosis, results in a wider range of variations among individuals.

In asexual reproduction, the division of a single bacterium results in the production of genetically identical offspring. Minor differences may arise due to small inaccuracies in DNA copying during cell division, but overall, the individuals are highly similar.
