Your question may be : In which structure do gametes usually unite to produce a zygote?
(1) A (3) C (2) G (4) F
The right answer is A, the gametes usually unit in the fallopian tube to form a zygote, then it will grow and move to the uterus (D) to form a placenta to develop a foetus.
Fallopian tube is also called as oviduct and serves to deliver the ova from ovary to the uterus. Ovulation results in release of egg from ovary which then enter the fallopian tube. Fallopian tube also serves as site of fertilization during which egg units with male gamete sperm to form a diploid zygote.
