Answer 2

Answer:

The odd one in the given set it terminologies is zygote.

Explanation:

The definitions of the following terms are:

• Oogonia - It is the diploid female gametogonia (initial stage of female gamete). Oogonia, which is the singular for oogonium is a tiny germ cell that further undergoes mitotic divisions to form the primary oocyte, which passes through mieotic divisions to form the female gamete ovum.
• Spermatogonia - It is the diploid male gametogonia (initial stage of male gamete). Spermatogonia, which is the singular for spermatogonium is a tiny germ cell that further grows to form the primary spermatocyte, which passes through mieotic divisions to form the male gamete sperm.
• Ootid - The haploid cell, produced by meiotic division of a secondary oocyte, that is a nearly mature ovum.
• Zygote - It is the first cell formed by the fusion of the male (sperm) and female (ovum) gametes.

Since, oogonia, spermatogonia and ootid the stages of gametogenesis (formation of gametes) of male and female gametes.

Whereas, zygote is the first stage after fertilization (fusion of male and female gamete).

Therefore, zygote is the odd term.
