Question

Meiosis generates gametes for sexual reproduction. The mixing of the blue and red chromosomes in the model below demonstrates a process known as crossing over. Crossing over occurs during prophase 1 of meiosis. Complete the statement based on the image of meiosis. "Crossing over is the exchange of genetic material between homologous pairs of chromosomes. This process __________ the variation in the resulting gametes because each contains __________ versions of the original genetic material."

Answer 1

"increases, different"

Crossing over swaps segments between homologous chromosomes during prophase I, creating new combinations of alleles so the gametes carry different versions of the original genetic material, increasing genetic variation.
