Select an option to attempt
Correct Answer: Option C
Explanation
Linkage groups = chromosomes. Each chromosome constitutes one linkage group (all genes on the same chromosome are linked, albeit with variable recombination between distant genes). The number of linkage groups = the HAPLOID chromosome number (), because each linkage group is one chromosome, and there aredifferent chromosomes. For a plant with: haploid number. Therefore there are 10 linkage groups. Classic example: Drosophila melanogaster has→ 4 linkage groups (4 chromosomes); humans have→ 23 linkage groups.
