Which process in meiosis produces new combinations of alleles on a chromosome?
Answer and explanation
Correct answer: D. Crossing over between non-sister chromatids of homologous chromosomes in prophase I
- Step 1: Chiasmata form between homologues in prophase I. Step 2. Segments are exchanged. Answer: crossing over. Why not the others: these do not create new allele combinations on one chromosome.
