Answer
Mutation is the primary source of genetic variation in organisms that reproduce asexually, such as amoebas. These mutations can occur due to various environmental factors or errors during DNA replication, leading to new traits and variations within the population.
Step 2
B. random fusion of gametes.

Answer
This option is not applicable since amoebas reproduce asexually and do not undergo gamete fusion, as gametes are involved in sexual reproduction.
Step 3
C. chiasma formation and crossing over.

Answer
Chiasma formation and crossing over are processes related to sexual reproduction and meiosis, which are not relevant to the asexual reproductive strategy of amoebas.
Step 4

Answer
Independent assortment of chromosomes occurs during meiosis and is a mechanism of genetic variation in sexual reproduction. It does not apply to asexual reproduction in amoebas.
