Based on standard genetics, recombinant chromosomes arise from crossing over during meiosis in the parent, producing gametes that carry novel combinations of alleles not present in the parental chromosome arrangement. Among gametes, those that show recombinant chromosome content are the ones that have undergone crossing-over between homologous chromosomes. Direct answer:
- The gametes that contain one or more recombinant chromosomes are the ones that show evidence of crossing-over between homologous chromosomes, i.e., gametes with mixed parental alleles at loci that were originally linked.
If you can share the specific genotype or chart of the gametes (A, B, C, D, etc.) and the marker positions, I can identify precisely which labeled gametes contain recombinant chromosomes.
