Here is ur Answer:

☆Human Beings :

In humans, biological sex is determined by five factors present at birth: the presence or absence of a Y chromosome, the type of gonads, the sex hormones, the internal genitalia (such as the uterus in females), and the external genitalia.

☆Honey Bees:

In honeybees, the drones (males) are entirely derived from the queen, their mother. The diploid queen has 32 chromosomes and the haploid drones have 16 chromosomes. Drones produce sperm cells that contain their entire genome, so the sperm are all genetically identical except for mutations.

Answer 2

Explanation:

In honeybees, the drones (males) are entirely derived from the queen, their mother.

The diploid queen has 32 chromosomes and the haploid drones have 16 chromosomes.

Sex determination in honey bees is initially due to a single locus, called the complementary sex determiner (csd) gene.
