• A. A small non-motile female, gamete and large motile male gamete
• B. A large non-motile female gamete, and a small motile male gamete
• C. A large non-motile female gamete and a small non-motile male gamete
• D. A large motile female gemete and a small non-mbtile male gamete.

Answer 1

Answer: (B)

A large non-motile female gamete, and a small motile male gamete

In oogamy, fertilization involves the fusion of a large non-motile female gamete and a small motile male gamete. The large motile female gamete is the ovum which is produced in the ovary. The ovum after maturation is released from the ovary under the influence of LH hormone. The small motile male gametes are known as sperm which is produced in the testis. The two dissimilar gametes fuse to form a diploid zygote by the process of syngamy.

So, the correct answer is option B.
