Question

during fertilization:
a the egg cell replicates itself to make double the amount of dna
b the spermatocyte creates 4 sperm cells through meiosis
c the sperm cell fertilizes the egg creating a zygote with 46 chromosomes.
d the oocyte replicates to produce 1 final egg and 3 polar bodies

Explanation:

• Option A: Egg cell does not replicate itself during fertilization. DNA replication occurs before meiosis in germ cells.
• Option B: Spermatocyte creating 4 sperm cells through meiosis is part of spermatogenesis (sperm production), not fertilization.
• Option C: During fertilization, a sperm (23 chromosomes) fuses with an egg (23 chromosomes) to form a zygote (46 chromosomes).
• Option D: Oocyte producing 1 egg and 3 polar bodies is part of oogenesis (egg production), not fertilization.

Answer:

C. The sperm cell fertilizes the egg creating a zygote with 46 chromosomes.
