Metaphase I
Prophase I
Telophase I
Interphase
Anaphase I
Correct answer:
Prophase I
Explanation:
Crossing over occurs during prophase I when parts of the homologous chromosomes overlap and switch their genes.
Example Question #1 : Understand Causes Of Genetic Variation
Which of the following affect the frequency of chromosomes of two linked genes crossing over?
Possible Answers:
Size of the gene
Size of the chromosome
Whether the genes are dominant or recessive
Distance between the genes
