Double reduction is a phenomenon that two sister chromatids of a chromosome sort into the same gamete. |
|
The complete series of events from zygote formation to gamete production constitutes the plant life cycle. |
|
The implantation into a human being of an animal gamete or embryo is banned. |
|
These are distinguished from nonreproductive adults by the presence of natatory setae and an enlarged medial region for gamete storage. |
|
Instead, species that differ in timing of gamete release tend to constitute genetically distinct clades. |
|
Each of these processes becomes a male gamete termed a microgamete which is equivalent to a mammalian spermatozoon. |
|
The law of segregation says that the two alleles are separated in the formation of the gametes, with each gamete receiving only one allele. |
|
There has been evolutionary growth in the technology of in vitro fertilisation and the gamete intrafallopian transfer programme. |
|
Note that migration always changes the state of the entire segment, because a gamete either does or does not migrate. |
|
The formation of the female gamete can be subdivided into two stages, megasporogenesis and megagametogenesis. |
|
In jurisdictions where this kind of policy has been implemented, as we heard last week, gamete donations have continued. |
|
In fact, I personally am aware of at least one instance where, with an anonymous gamete donor, an individual has been brought to life. |
|
Surrogates and gamete donors incur real but unquantifiable costs in the course of helping infertile couples build families. |
|
In other words, it often results in increased birth deformities, reduced survival, reduced viability-reduced gamete production. |
|
Therefore, it is important that the issues of surrogate mothers, gamete conservation and donations be covered by regulations. |
|
Application Research on embryos requires the consent of the gamete donors. |
|
During fecundation, a male gamete meets a female gamete, both gametes being taken completely randomly among all produced gametes. |
|
Consequently, it is not unreasonable or unethical to suggest that surrogates and gamete donors be entitled to reimbursement of these costs. |
|
Will the law require consent to embryo research only from the gamete providers, as is currently required in the tri-council policy statement? |
|
It added a specific authority to regulate the number of children that could be born from a single gamete donor. |
|
|
One can speak of a gamete donor in the singular, but the human embryo has two parents, a mother and a father, whether anonymous or known. |
|
In many species with gametes of different sizes, sexual crosses typically produce progeny with mitochondrial DNA inherited from the larger gamete. |
|
This is why we believe that surrogacy and gamete donation would be the best option for us to solve our infertility. |
|
The moral complexity of genetic engineering, gamete selection and foetal surgery ran way ahead of old concepts of right and wrong. |
|
In common with in vitro fertilisation, a gamete intrafallopian transfer cycle begins with superovulation to recruit multiple follicles and is followed by egg retrieval. |
|
Males arise spontaneously through nondisjunction of the X chromosome during gametogenesis and the subsequent fusion with a normal gamete, yielding an XO individual. |
|
Particularly in oogamous species, uniparental inheritance of mitochondria has been attributed to the small number of mitochondria in the male gamete. |
|
I assume that each new diploid individual results from the random fusion of a male and a female gamete and that its gender is independent of its autosomal genes. |
|
The embryos of all sexually reproducing organisms develop from a single cell, formed by the fusion of a male and a female gamete at fertilization. |
|
Is there a ban in terms of the local framework of family law to clarify and protect the gamete donors in family law? |
|
What we've heard over here is that since the release of that discussion paper there has been a measurable decline in gamete donation. |
|
After all, for this type of research, gamete donors will have to give their consent. |
|
In contrast, legislation on gamete donation takes pains to ensure that donors have no tie of filiation with the child. |
|
And current moves to give children born through reproductive technologies, using donated gametes, access to the gamete donor's identity show a deep human need to know our biological family origin. |
|
Only will survive the fertilized gametophytes, that is to say, their oosphere, the female gamete, was fertilized by an anterozoide, the male gamete. |
|
We felt that although the issue of the gamete supply was an important one, it didn't override the interests of people created as a result of infertility treatment through donor insemination to know their origins. |
|
By surrounding the whole process of gamete donation with secrecy, with a sort of occultism, is the government not helping to maintain the culture of secrecy that surrounds sterility, which is not good? |
|
This amplifies the effects of genetic predispositions as a child ages. Parental genetic endowment can also affect children who have not, through the vagaries of gamete formation, inherited the relevant DNA directly. |
|
I recommend you agree to compensate gamete donors. |
|
We recommend that all gamete donation include identifying information that can be given to the resulting child, perhaps after they attain the age of majority. |
|
|
It is the same with surrogacy as it is with gamete donation. |
|
I believe that should reimbursements to surrogates and gamete donors be limited to receiptable expenses only, the available pool of surrogates and donors will decrease significantly. |
|
Many plants can generate a genetic clone through a process called vegetative reproduction, which does not involve meiosis, gamete formation, or fertilization. |
|
Because of the biological features of the plant, which is a sterile triploid propagated only by division of the corms, only evolutionary change linked to gamete reproduction will modify its genetic character. |
|
Finally, the way to ensure safety and quality in gamete donation specifically, as in blood donation, is not only through it being free of charge but also through ensuring availability. |
|
While this type of situation exists in some surrogacies, in other cases, a donated gamete from a foreign donor is used to create the embryo. |
|
The effect of advancing paternal age on pregnancy and live birth rates in couples undergoing in vitro fertilization or gamete intrafallopian transfer. |
|
Advances in IVF's effectiveness and its lower cost have pushed other technologies, such as gamete intrafallopian transfer and zygote intrafallopian transfer, out of favor. |
|
Gamete intrafallopian transfer can be used only in women who have at least one patent fallopian tube. |
