Give reasons for the following:
A male honey bees has 16 chromosomes where as its female has 32 chromosomes.

Explanation

In honey bees both sexual reproductioni and parthenogenesis occurs, and it is describted as incomplete parthenogenesis. It is a kind of natural parthenogenesis.
During sexual reproduction the fertilized eggs (zygotes) develop into queen bee and worker(females). The unfertilized eggs develop into drones (males). This honey bees are called parthenogenesis animals.
In honey bees the normal chromosomal number in a a cell is `2n=32`. Gametes (sperms & egg) will have only `n=16` chromosomes since they are haploid. The female bees are formed by fertilization of gameters.
sperm `(n)+` egt (n)`=2n`
Therefore they have 32 chromosomes. Since the drones (male) are formed from unfertilized egg (n) they have only 16 chromosomes. Honey bees show incomplete parthenogenesis.
