(Paradoxically, the law would allow Trounson to proceed with the new techniques if he were to transfer the embryos to a woman's uterus; but he considers that unethical when the normality of embryos resulting from the techniques has not been assessed.) Trounson has therefore proposed fertilizing ova and examining them before syngamy has taken place.

In October 1987 the Victorian Parliament resolved this impasee by amending the 1984 legislation to allow research on specially created fertilized ova up until the time of syngamy.

Australian developments in reproductive technology

These include 1) the cortical reaction, 2) completion of meiosis 2 with extrusion of the second polar body, and 3) formation of pronucleus and syngamy. The timing of these events in the hamster is illustrated in Figure 14-11.

This process is known as syngamy. Syngamy begins with the apposition of the two pronuclei.

Chapter 14: Establishing pregnancy: from coitus to syngamy

Two stains were used in this study to visualize the nuclei within ovarian, coelomic, and spawned oocytes in order to (1) determine the stage and location of oocytes at sperm-egg fusion and (2) describe nuclear events during egg maturation, pronuclear migration, and syngamy. The DNA-specific fluorochrome bisbenzimide H33342 was used at 10 [[micro]gram]/ml by diluting a 100 [[micro]gram]/ml stock in 475 mM sodium chloride and 25 mM potassium chloride 1:10 with 0.2 [[micro]meter] filtered seawater.

Second, the time elapsed since syngamy may be an important regulatory signal.

The effect of sex on the variance in fitness and mean fitness

If the protoplasts were from haploid cells (as from anther or ovule culture), new diploid cells could be produced in a sort of artificial syngamy (parasexual or somatic hybridization).

A most important consequence of sexual reproduction is the generation of novel diploid genomes through syngamy of two haploid, meiotically recombined gametes.

Glossary

Generations are nonoverlapping and syngamy (fusion of gametes) is synchronized, as would result from selection to maximize fertilization success.
