Question

what ensures the viability of one gamete in oogenesis?
the viable daughter cell goes through cell death.
the elimination of non - viable daughter cells through cell death.
the viable daughter cell absorbs organelles and resources from the three non - viable daughter cells.
the fusion of genetic material from the viable daughter cell to the non - viable daughter cells.

Explanation:

During oogenesis, one viable egg cell (ovum) is produced. The other daughter cells (polar bodies) are non - viable. These non - viable polar bodies undergo cell death (apoptosis). This elimination of non - viable cells ensures that the resources are concentrated in the single viable gamete (the ovum).

• The first option is incorrect because the viable daughter cell does not go through cell death.
• The third option is incorrect as there is no absorption of organelles and resources from non - viable cells to the viable cell in the context of ensuring gamete viability in the way described.
• The fourth option is incorrect as there is no fusion of genetic material from the viable to non - viable cells in oogenesis for the purpose of ensuring gamete viability.

Answer:

The elimination of non - viable daughter cells through cell death.
