Use the diagram above to answer the question that follows:
Recombination of genes at fertilization is represented by the part labelled
- I
- II
-
III
- IV
The correct answer is: C
Explanation
During prophase I, homologous chromosomes from each parent pair up and exchange genetic material, a process known as crossing over. This process creates new combinations of genes in the resulting gametes. When two gametes unite during fertilization, the offspring will have a unique combination of DNA.
Genetic recombination during fertilization takes place in the prophase I stage of meiosis ( part labelled III)
