Exempel på hur man kan använda GAMETE i en mening

• The type of gamete an organism produces determines its sex and sets the basis for the sexual roles and sexual selection.
• During sexual reproduction, a male and a female gamete fuse to form a zygote, which develops into an offspring that inherits traits from each parent.
• A spermatozoon is a moving form of the haploid cell that is the male gamete that joins with an ovum to form a zygote.
• The egg cell or ovum (: ova) is the female reproductive cell, or gamete, in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one).
• An archegonium (: archegonia), from the Ancient Greek ἀρχή ("beginning") and γόνος ("offspring"), is a multicellular structure or organ of the gametophyte phase of certain plants, producing and containing the ovum or female gamete.
• The pollen tube acts as a conduit to transport the male gamete cells from the pollen grain—either from the stigma (in flowering plants) to the ovules at the base of the pistil or directly through ovule tissue in some gymnosperms.
• a female, an organism producing ova gametes that fuse with the male gamete during sexual reproduction, typically having two X chromosomes in the XY and X0 sex determination systems.
• In hermaphroditic reproduction, each of the two parent organisms required for the formation of a zygote can provide either the male or the female gamete, which leads to advantages in both size and genetic variance of a population.
• A granulosa cell or follicular cell is a somatic cell of the sex cord that is closely associated with the developing female gamete (called an oocyte or egg) in the ovary of mammals.
• The gametophytes (the haploid gamete producers) of this plant develop from very small spores that float in the air and are deposited on moist tree branches.
• This can be seen as early as oogenesis, for the female sacrifices gamete number for gamete size to better increase the survival chances of the potential zygote; a process more energetically demanding than spermatogenesis in males.
• The infected oyster becomes stressed, its tissues are pale in color, its gamete production is retarded, its growth slows, it becomes emaciated, its mantle shrivels and pulls away from the shell, and it may develop pockets of pus-like fluid.
• However, since it is unlikely the same essential gene is mutated in independent gametes, and if loss of the essential gene did not kill the gamete itself, downstream gamete fusion often allows for survival of the resulting zygote and organism, as the now heterozygous non-functional mutated allele may be rescued by the still wildtype allele provided by the other gamete.
• fortunata features a standard process in which immature female gamete cells (oogonia) undergo mitosis to form oocytes.
• He worked with reproductive technology and pioneered gamete intrafallopian transfer (GIFT), as well as working on research linking fertility and marijuana usage, and investigated the use of GnRH analogues with Andrew Schally.
• Sperm (: sperm or sperms) is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction (forms in which there is a larger, female reproductive cell and a smaller, male one).
• The bird egg is a fertilized gamete (or, in the case of some birds, such as chickens, possibly unfertilized) located on the yolk surface and surrounded by albumen, or egg white.
• In oogamy the large female gamete (also known as ovum) is immotile, while the small male gamete (also known as spermatozoon) is mobile.
• Trisomy 21 is the cause of approximately 95% of observed Down syndrome, with 88% coming from nondisjunction in the maternal gamete and 8% coming from nondisjunction in the paternal gamete.
• Oospores are made after the male gamete, antheridium, and female gamete, oogonium, undergo fertilization and then sexual recombination (meiosis).
