Definition of gamete in English: gametenoun ˈɡamiːt Biology A mature haploid male or female germ cell which is able to unite with another of the opposite sex in sexual reproduction to form a zygote. Example sentencesExamples - Meiosis is the process by which diploid organisms produce haploid gametes capable of sexual reproduction.
- This virus does not integrate into the fly chromosomes and is only vertically transmitted through male and female gametes.
- 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.
- Zygotic embryogenesis in animals and plants starts with the fusion of the haploid female and male gametes, giving rise to a diploid zygote.
- Once within the gonads, the germ cells differentiate as either male or female gametes.
Derivatives adjective ɡəˈmɛtɪk Biology If gametic and/or zygotic selection occurs whereby certain gametes or zygotic combinations have a reduced chance of survival, progeny distributions are skewed and are said to exhibit segregation distortion. Example sentencesExamples - Several gametic and zygotic reproductive barriers were found in a cross between Japonica and Indica rice varieties.
- Indeed, usually the marker phenotypes do not provide the gametic phase of the chromosomes (which allele originates from which parent), for example, in the case of a double or multiple heterozygote.
- Simultaneous analysis of the haploid megagametophyte and diploid embryo in a seed allows the female and male gametic contributions to the zygote to be separated.
- These observations demonstrate that a mechanism contributed by the cytoplasm of the wild-type gametic cell recognizes abnormal-length flagella and restores length control.
Origin Late 19th century: from modern Latin gameta, from Greek gametē 'wife', gametēs 'husband', from gamos 'marriage'.
