BlackTom AI · Accepted Answer

Question at position 43 asks you to select any cause of mutations.

Option 1: Independent assortment
This refers to how alleles of different genes separate during meiosis, generating genetic variation in offspring. It is a mechanism of inheritance, not a direct cause of mutations in DNA. Therefore, this option is incorrect as a cause of mutations.

Option 2: Environmental factors
Environmental factors such as radiation, certain chemicals (mutagens), and other external stresses can damage DNA or alter its structure, leading to mutations. This makes this option a correct cause of mutations.

Option 3: Random fertilization
Random fertilization increases genetic diversity by combining gametes in many possible ways, but it does not cause new mutations in DNA. It affects allele combinations, not the mutation rate itself, so this option is incorrect as a cause of mutations.

Option 4: Errors in DNA replication
During DNA replication, mistakes can be introduced and, if not corrected by proofreading or mismatch repair, become mutations in the daughter DNA. This is a direct mechanism producing mutations, so this option is correct.

In summary, the correct mutation causes among the given options are Environmental factors and Errors in DNA replication, while Independent assortment and Random fertilization relate to inheritance and variation rather than to mutations themselves.
