• The function of these unfertilised eggs are nutritional, not reproduction.
• This also happens in salamander eggs, even when they are unfertilised.
• Iran bans sperm donation but allows donation of both fertilised and unfertilised eggs.
• Unfertilised eggs become haploid males; fertilised eggs grow into diploid females and queens.
• The zona pellucida is a thick membrane that surrounds the unfertilised eggs of mammals.
• Adults are thelyotokous, females being produced from unfertilised eggs, and males are rare.
• Workers are known to produce their own eggs, but these eggs are unfertilised and hatch into male ants.
• Habitats are primarily on unfertilised calcareous grassland; this includes chalk download, coastal grassland and undercliffs in Britain.
• During reproduction, the eggs remain unfertilised and thus have half the number of chromosomes of a normal cell.
• The mature, unfertilised eggs of the yellowtail trumpeter are small and spherical, having an average diameter of 560 ?m.
• It is generally conceived that the unfertilised eggs are ingested by the snail, but there has been no direct observation.
• Male ticks do not engorge from the host, they wander over the host searching for unfertilised females with which to mate.
• Many aphids are capable of parthenogenesis, producing young from unfertilised eggs; this helps them to reproduce extremely rapidly in favourable conditions.
• The smooth surfaced currant gall generation appears in April and lay unfertilised eggs in the staminate catkins or occasionally the developing young leaves.
• The smaller males are, like other Hymenoptera, hatched from unfertilised eggs and are provisioned with smaller spider prey than female eggs.
• After the larvae have hatched, the female lays up to as many as 25, 000 unfertilised eggs upon which the larvae feed.
• She seems to preferentially allocate unfertilised eggs to the earliest instars that she parasitises, resulting in more male offspring occupying smaller aphid nymphs.
• Parthenogenesis ( reproduction from unfertilised eggs ) is exceptional, and has only been recorded in nature in female " Ischnura hastata " on the Azores Islands.
• Secretary birds lay two to three oval, pale-green eggs over the course of two to three days, although the third egg is most often unfertilised.
• The largest cells known are the nerve cells of a giant squid that can be 80 feet long . . . and the heaviest is an unfertilised ostrich egg.
