The correct answer is 12 and 12. Explanation & Key Takeaways: • Male grasshopper • Male has a total of 23 chromosomes. • 22 + XO(sex chromosome). • The haploid number will have to be 12 i.e (11+X). • Hence the number of linkage groups in male grasshopper is 12. • Female grasshopper • Female has a total of 24 chromosomes. • 22 + XX(Sex chromosome). • XX are two similar chromosomes, which is considered as one. • Hence haploid number still unchanged which is 12 (11+X). • Hence the number of linkage groups in female grasshopper is also 12. • Hence the correct answer is 12 and 12. Important Notes: • Grasshoppers are a group of insects belonging to the suborder Caelifera. • They are among what is probably the most ancient living group of chewing herbivorous insects. • Dating back to the early Triassic around 250 million years ago. • Grasshoppers are typically ground-dwelling insects with powerful hind legs that allow them to escape from threats by leaping vigorously.
