For the self-fertilized
group, 12 individuals randomly selected from the adult parents were placed individually in an 80-L bucket and allowed to spawn to produce self-fertilized
Egg number per clutch varies considerably between the two development modes, and preliminary results indicated that eggs per clutch also varied among mating types (unfertilized, self-fertilized
, or paired).
The fact that DBGMF seeds occurred in offspring of self-fertilized
LBGMF lines indicated that the 4E chromosome was transmitted through both female and male gametes.
We hypothesized that reduced resources may constrain the development of self-fertilized
fruits more than outcrossed fruits and, therefore, that resource reduction will increase the proportion of outcrossed progeny.
In contrast, 51 animals produced gametes that had a self-fertilization rate of greater than 90%; of these, 16 were 100% self-fertilized
The grass produces dimorphic seeds from terminal panicles of potentially outcrossed flowers and self-fertilized
cleistogamous flowers in the lower leaf sheaths (cleistogenes) (Weatherwax 1928, Clay 1983, Cheplick and Clay 1989).
0] PHV119 and PHV122 were self-fertilized
, and their progeny screened by PCR analysis for the presence of the bar gene, with both PHV119 and PHV122 transferring the foreign gene to the [T.
At anthesis, six plants of F497 were self-fertilized
and six others were crossed with F252 as male.
Experimental designs used in this study to test the viability of self-fertilized
offspring also provide information on relative gender success in test crosses.
Wang (1947), by studying embryological development of cross and self-fertilized
kernels on the same ear, observed the same phenomenon, but with a high reciprocal or female effect, and showed that the advantage of cross fertilization is greater in the early stages.
It remains possible that, at that time, paired snails actually mainly self-fertilized
, masking inbreeding depression.
5% of self-fertilized
progeny would have unique phenotypes at the Pgi-2 locus.
