For your first question, the statement that does not accurately describe what occurs during the process of meiosis is:
C: Meiosis produces four identical gametes, either egg or sperm.
This statement is incorrect because meiosis produces four genetically distinct gametes due to processes like crossing over and independent assortment.
For your second question, the statement that does not apply to meiosis, sexual reproduction, and genetic variation is:
A: Meiosis is preceded by DNA replication of chromosomes in the nucleus of the mother cell.
While DNA replication does occur before meiosis (during the S phase of interphase), this statement is more of a description of the cell cycle rather than a direct mechanism that enhances genetic variation. The other options involve processes that directly contribute to genetic variation.
