Answer:

In the words of a well trained scientist:

Male heterogamety: In this type, a male individual produces two different types of gametes. Thus, the sex of the offspring is determined by the sperm. it involves two types of sex-determining mechanisms; XO type and XY type.

i. XO type (XX-XO type): It is observed in a large number of insects e.g. Grasshopper. The number of chromosomes is different in male and female individuals. It is clear that all eggs (ova) bear an additional X-chromosome besides the autosomes while only 50% of the sperms bear X-chromosomes. In grasshopper, eggs fertilized by (A+X) type sperm become females while those fertilized by (A+O) type sperm become males. Therefore, sperm determines the sex of the offspring. Due to the involvement of the X-chromosome in sex determination, it was designated to be the sex chromosome.

Explanation:

Honey bees can survive, unlike humans, with no fertilization. Birds have chromosomes and DNA that mostly determine colors of things like feathers and skin and the beak.

Humans have a XY sex configuration. Sperm determine the sex also in humans. sperm can carry either the X or the Y chromosome and the female egg is always X. If a X sperm unites with an egg, you get a female! If a Y sperm unites with an egg, you get a male!

I hoped this helped!
