The fertilised cell is quite another thing from the unfertilised cell.

The University of Bath scientists started with an unfertilised egg in their experiments.

In the young, unfertilised ovaria of many Vandeae there seemed an infinitude of ovules.

He discovered that male bees come from the unfertilised, and female bees only from the fertilised, eggs.

Interestingly, although expressed in the unfertilised egg, this enzyme functions only during one round of replication in the eight-cell embryo.

The biological control method involves releasing sterile male catfish into lakes to disrupt reproduction by causing catfish eggs to be left unfertilised.

For the eggs of certain animals membrane-formation is all that is required to induce a complete development of the unfertilised egg, e.g.

The writer found that we can produce this membrane in the unfertilised egg by certain acids, especially the monobasic acids of the fatty series, e.g.

Unfertilised ovum of an echinoderm (from Hertwig).
