Question : Give reasons for the following: (a) Some organisms like honey bees are called parthenogenic animals (b) A male honey bee has 16 chromosomes whereas its female has 32 chromosomes |
|
Answer» Solution :(a) Among honey bees, the queen bee and worker bees develop from fertilized eggs whereas the drones develop from unfertilized eggs. Hence the honey bees are PARTHENOGENETIC animals showing incomplete parthenogenesis. (b) Female honey bees (Queen or worker bees ) are diploid having 32 chromosomes since they develop from the fertilized egg. On the other hand, the MALE honey bees (drones) develop from unfertilized egg possessing only 16 chromosomes (I.e., HAPLOID) |
