Solution
The process that introduces genetic variability among the gametes is meiosis only.
Here's why:
-
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is what leads to genetic diversity in organisms.
-
During meiosis, one cell divides twice to form four daughter cells. These four daughter cells only have half the number of chromosomes of the parent cell.
-
In the first division (Meiosis I), the chromosomes make copies of themselves. Then, these copies exchange genetic material in a process called crossing over. This is the main reason why meiosis introduces genetic variability.
-
In the second division (Meiosis II), the
