gamete

The main significance of the work is not to attempt to generate gametes for couples who do not produce them naturally.

Genetic drift is change in the genetic composition of a population arising as a consequence of sampling of gametes in a finite population.

senescent period Old age, a time when fish growth is extremely slow, arrested or negative and gametes are inferior or not produced.

Polyploids can arise by somatic doubling, by the fusion of unreduced gametes, and by means of a triploid bridge.

Another form of apomixis in which seeds develop from unfertilized gametes can also be termed parthenogenesis.

"Maybe that is affecting gametes in ways that are going to have consequences for the next generation, " she says.

Karyogamy The fusion of two nuclei that exist within a common cytoplasm, as occurs in the formation of the zygote from two gametes.

Sexual reproduction The formation of new individuals by fusion of two nuclei or sex cells ( GAMETES ) to form a diploid ZYGOTE.

The donation of gametes or embryo used ines cell research should be voluntary and valid informed consent must be obtained.

Generally meiosis occurs before gamete formation, resulting in the gametes being haploid (having half the normal number of chromosomes).

A comparison of chromosomes in the gametes of a related, sexually-producing lizard species (above) and the whiptail (below).

In both the male and female gametes, GSH is involved in the protection of these cells against oxidative damage.

Meiosis, which usually precedes spore or, sometimes, gamete formation, halves the chromosome number to produce haploid gametes .

The basic set of chromosomes in a species is the haploid set, usually found in the gametes.

The formation of unreduced gametes leads to spontaneous chromosome doubling, which has a great significance in the origin of common wheat.

Diplont A diploid organism that represents the vegetative stage in life cycles in which haploidy is restricted to the gametes.

Gametes showed intensive positive phototaxis, after syngamy, motile zygotes showed negative phototaxis.

In unicellular organisms whole individuals may unite but in most multicellular organisms only the gametes combine.

The formation of a zygote by the union of genetically different gametes.

The drones such as bees, body cells contain the gametes of this species were off the number of individuals, called haploid.

The cell formed by the union of two gametes, especially a fertilized ovum before cleavage.

Meiosis occurs in gametes before the formation of a certain time, it is a nuclear male and female gametes are single-fold.

The eyespot of unicellular and colonial algae and their gametes and zoospores contains globules of orange or red carotenoid pigments.

Autopolyploids may arise from the fusion of diploid gametes that have resulted from the NONDISJUNCTION of chromosomes at meiosis.

those in which male and female gametes are borne on different individuals are termed DIOECIOUS.

The formation of male gametes includes germ cell and vegetative cell differentiation and the occurrence of male gametophyte.

broadcast spawners Fish which release their gametes into the water, where fertilization may occur; without parental care.

Cryptogam In early classifications, any plant that reproduces by spores or gametes rather than by seeds.

First are those individuals or couples who lack the gametes (eggs or sperm) needed for sexual reproduction.

immunizing mosquitoes against gametes, the sexual stage of Plasmodium.

The diploid condition is restored when the nuclei of two gametes fuse to give the zygote.

Enticed by the light, the males also contribute gametes to the X-Files-esque reproductive cloud.

Unreduced gametes are common in plants and likely represent the most frequent route to polyploidy .

an animal that produces gametes (ova) that can be fertilized by male gametes ( spermatozoa ).

Scientists must either adapt the culture to produce more gametes or develop some other way to grow them in quantity.

In angiosperms it gives rise directly to the two male gametes or generative nuclei.

Based on experiments with mice, Weismann proposed that hereditary information in gametes transmitted traits to progeny.

Sale and purchase of human gametes, fertilized eggs, embryos and fetal tissue.

Hybrid sterility The reduced ability of some hybrids to produce viable gametes.

The transmission frequency of gametes with 6V in heterozygous plants were decreased clearly.

A large multinucleate spore formed by union of similar gametes, as in algae or fungi.

reproduced by fusion of gametes of different ancestries.

An organ in animals that produces gametes, especially a testis or an ovary.

That may explain why pilots often see red, 10-kilometer-long slicks of coral gametes a couple of days after a full moon.

It usually occurs between gametes or protoplasm.

Most female gametes have two synergids that play a key role during fertilization in more than 80% angiosperms.

In fish, the term egg usually refers to female haploid gametes .

Objective: TO sum up clinical research and application of gametes intrauterine transfer(GIUT) in our hospital.

In general, the transmission ratios of gametes with 6R were decreased clearly.

In these groups, gametes are produced by mitosis.

Meiosis is the process of cell division that produces gametes in both sexes.

The union of male and female gametes to form a zygote.

They now know that when the gametes are formed, certain epigenetic markers remain and are passed on to the offspring.

In the human reproductive process, two kinds of sex cells, or gametes (pronounced: gah-meetz), are involved.

In general, the transmission ability through the female gametes was higher than that through the male gametes .

When the gametes are readily distinguished as male or female, other therms may be used such as ANTHERIDIUM, ARCHIEGONUM, or OOGONIUM.

Informatics Characters between Sexual Gametes in Inbreeding Population

Individuals producing both male and female gametes are termed hermaphrodite if in the same flower or MONOECIOUS if in separate flowers;
