单词	cytogenetics
释义	cytogenetics /ˌsʌɪtəʊdʒəˈnɛtɪks / plural noun [treated as singular] Biology The study of inheritance in relation to the structure and function of chromosomes.She became one of the founders of the field of maize cytogenetics, the genetic study of maize at the cellular level.... Prenatal diagnosis for the detection of chromosomal abnormalities was carried out by conventional cytogenetics in the present study in the foetuses of high risk pregnancies in women attending a tertiary care facility in north India. Laboratories performing cytology, cytogenetics or histocompatibility testing will undergo on-site inspection every two years. Derivatives cytogenetic /ˌsʌɪtə(ʊ)dʒəˈnɛtɪk / adjective ... Chromosomal damage can be assessed by the cytogenetic analysis of chromosomes at metaphase. In vivo cytogenetic studies suggested the induction of chromosome damage in Chinese hamster bone marrow cells. Ultrastructure and cytogenetic studies indicate that the rhabdoid cells have a similar origin to those of classic clear tumor cells. cytogenetical adjective ... Cytogenetical techniques for the analysis of meiosis in Arabidopsis, including the application of fluorescence in situ hybridization for chromosome identification, have improved dramatically in recent years. DNA content and cytogenetical observations suggest that this grass is an allotetraploid. cytogenetically adverb ... Some women, including those in older age groups and those who have had repeated failure of in vitro fertilisation, are more likely to produce cytogenetically abnormal embryos, which are not capable of normal development. The lost chromosome may form a micronucleus that can be detected cytogenetically. Ectopic exchanges between transposable elements situated in heterozygous positions around a locus at which mutations are screened can lead to cytogenetically detectable events. cytogeneticist /ˌsʌɪtəʊdʒəˈnɛtɪsɪst/ noun ... To offer a safe effective service, a multidisciplinary team needs to be established, including specialists in in vitro fertilisation, clinical geneticists, genetic counsellors, cytogeneticists, and molecular biologists. Since at that time I was one of the relatively small set of persons working seriously with human chromosomes, I had made friends with many other cytogeneticists throughout the world or at least was known to them. Early cytogeneticists quantified genomes by analyzing the partition in chromosomes that were counted in cytological preparations.
