Question

Identify the correct sequence of events in sexual reproduction.

1. Syngamy

2. Zygote formation

3. Gametogenesis

4. Embryogenesis

5. Gamete transfer

• A. 3 → 5 → 2 → 1→ 4
• B. 1 → 2 → 3 → 4 → 5
• C. 3 → 5 → 1 → 2→ 4
• D. 5 → 4 → 3 → 2→ 1

Answer 1

The correct option is C

3 → 5 → 1 → 2→ 4

During sexual reproduction after gamete formation or gametogenesis, haploid gametes move towards each other, that is a process called gamete transfer and they fuse together. This process is called syngamy or fertilisation and it leads to the formation of a diploid zygote. The zygote then develops into an embryo in a sequence of events that is collectively termed as embryogenesis.
