So far the experiment has been running for 11 sexual generations and the data are starting to come in.

Over sexual generations c2-m4 continues to be unstable.

These develop into small oval galls which produce the sexual generation of wasps.

Only this third batch of buds eventually grows into gonozooids - the sexual generation.

The sexual generation consists of individuals featuring eight muscle bands, each having male or female gonads.

So, sexual generation is the means whereby the past influences of changing conditions can be accumulated and combined with present ones to ensure continued variability.

Multiple rounds of asexual reproduction between sexual generations is not uncommon in benthic forms.

Gall wasps of the family Cynipidae produce a single sexual generation within a structure that resembles an apple.

The early trees, like their predecessors, the mosses, existed in two alternating forms, a sexual generation and an asexual one.

In the simplest form, the organism arising from sexual generation produces offspiring unlike itself, agamogenetically.

Thanks to the impressionability of immature organization, hereditary adaptive variation accompanies sexual generation in changing conditions.

The effects were seen in the generation in which the treatment was given and they were also observed in the following sexual generation.

About 350 million years ago, some appeared in which the sexual generation no longer grew flat on the ground, but up in the crowns of the trees.

However, the macronucleus is propagated only during the vegetative part of the life cycle and is not transmitted from one sexual generation to the next.

Hitherto, it had been achieved by the male cells swimming through water, a process which demanded that the sexual generation be small and close to the ground.

For the nematode worm Caenorhabditis elegans, the mutation rate per effective genome per sexual generation is 0.036.

The sexual generation develops in spring in small conical galls that form on the male catkins of the Turkey oak.

The reproduction of fire corals is complex and involves an alternation of asexual and sexual generations.

He was soon making explicit, too, a fundamental teleological analogy, in which changing conditions are to sexual generation as sexual crossing is to asexual generation.

The micronucleus is the germline nucleus; i.e., it contains the DNA information passed down from one sexual generation to the next.

In reproductive biology, heterogamy is the alternation of differently organized generations, applied to the alternation between parthenogenetic and a sexual generation.

The wasps of the sexual generation are sometimes known by the synonym Andricus fecundator forma pilosus (DvL 1982).

Caused by the uncommon cynipid wasp, Andricus quercusramuli, the structure actually conceals as many as 20 true galls, each containing a single larvae of the sexual generation.

The emerging adult gall-wasps in spring are the sexual generation, producing both males and females, which fly to the common oaks to initiate the formation of the summer marble gall.

Although it can extend an individual life, continued grafting eventually brings death without issue; and likewise sexual generation in unchanging conditions brings death, extinction of the species, without issue.
