Sexual fertilization takes place
when a sperm from the male fuses into the egg cell of the female. Human cells contain 23 chromosomes and has a total of 46
pairs of chromosomes. A male has a total of 46 pairs chromosomes and gives 23 chromosomes
while a female has a total of 46 pairs of chromosomes and gives 23 chromosomes
to the offspring. These pairing are responsible to the trait of the offspring. The
formation of both male and female gametes creates a zygote. They will start to
form at the fallopian tube, down to the oviduct and into the uterus as it
continues to divide.
