Definition of unfertilized in English:

unfertilized

(also unfertilised)

adjective

  • Not fertilized:

    ‘an unfertilized egg’
    ‘unfertilized land’
    • ‘This involves taking an unfertilised female egg, removing the chromosomes, replacing them with one male's chromosomes, and fertilising it with another's sperm.’
    • ‘This year we will compare the results of crops grown with rock dust, manure, chemical fertilisers and an unfertilised control.’
    • ‘Another is through parthenogenesis - activating an unfertilised human egg so that it starts to divide like an early embryo.’
    • ‘There must be chemicals and proteins in the cytoplasm of an unfertilized egg that cause a nucleus to revert to an earlier stage of development.’
    • ‘In these mutants, the meiotic products remain in interphase in unfertilized eggs and undergo inappropriate DNA replication.’
    • ‘This process is known as parthenogenesis, where unfertilized eggs develop into embryos without sperm.’
    • ‘And since there is no way to tell fresh fertilized eggs from unfertilized ones without a microscope, your customers won't be able to tell either way.’
    • ‘Scientists based at Newcastle's Centre for Life have today been granted permission to carry out pioneering research to create stem cells from unfertilized human eggs.’
    • ‘Next, they took an unfertilized egg from a second sheep and removed its DNA, carefully sucking it out with a thin glass tube called a pipette.’
    • ‘In parthenogenesis, an unfertilized egg can start dividing and still produce a normal offspring.’
    • ‘As part of the collaboration, Wilmut is to apply to the Human Fertilisation and Embryology Authority for permission to collect fresh unfertilised eggs from women volunteers.’
    • ‘In some species the eggs may or may not be fertilized; fertilized eggs produce females, while unfertilized eggs produce males.’
    • ‘During copulation the female transfers unfertilized eggs to the male's ventral surface, where fertilization takes place.’
    • ‘Here, mating partners repeatedly alternate donation of a small parcel of unfertilized eggs, which is then immediately fertilized by their mate, who subsequently assumes the female role.’
    • ‘In most ants, females are typically produced by sexual reproduction, while males develop from unfertilized eggs.’
    • ‘Because the unfertilized eggs are naked protoplasts lacking cell walls, unfertilized eggs were used for these experiments in order to give the antibodies unimpeded access to the cell.’
    • ‘An unfertilised donated egg has all of its genetic material removed, leaving the cell empty.’
    • ‘Having found that cumulus cells yielded better results, unfertilised mouse eggs were enucleated and their donor's nuclei put in place.’
    • ‘We also isolated several mutants that produce unfertilized eggs or show an early arrest in embryonic development.’
    • ‘This tactic seems risky, because not all ovules get fertilized, and the unfertilized ones abort without storing nutrients.’
