| 词汇 | haploid |
| 释义 | haploid adjective uk /ˈhæp.lɔɪd/ us /ˈhæp.lɔɪd/ having a single set of chromosomes (= structures containing chemical patterns that control what a plant or animal is like) that comes from one parent only: 单倍体（只含有一个决定动植物性状的染色体组，从父母中的一方获得） a haploid cell单倍体细胞 Sex cells such as eggs and sperm are haploid.生殖细胞，比如精子或卵子，都是单倍体。 Compare diploid Cells actin anaphase anti-platelet assort axoplasm histochemistry histography homologous chromosomes infiltration intercellular neoplasia nerve fibre neurofibril neurofibrillary neuroglia teratoma tetrad thrombocyte thymocyte turgor Examples of haploidhaploid As such it was done without chromosomal replication : two haploids recombined their genomes and then separated as haploids again. Inability of mature oocytes to create functional haploid genomes from somatic cell nuclei. A subset of clones was verified more thoroughly by measuring under r40 magnification the sizes of the haploid colonies obtained after tetrad dissection. The primary spermatocytes divide meiotically to generate the secondary spermatocytes and haploid spermatids in successive divisions. It is considered that the mitochondria are maternally inherited and are, therefore, haploid (clonal). A detailed linkage map of rainbow trout produced using doubled haploids. Experiment 2 compared cell number and incidence of apoptosis in diploid and haploid parthenotes. If selection occurs during the haploid phase, haploid selfing leads to the same population-level consequences as haploid apomixis. This is done below and it is found that the kind of epistasis also strongly influences the (haploid) error threshold. The same will be true if the ratchet has advanced sufficiently far that a substantial proportion of loci are fixed within haploid sets. This might be expected when haploids are compared with heterozygotes, but not necessarily expected when haploids are compared with homozygous mutant diploids. In this experiment, the aim was to measure growth rate of diploids in conditions as similar as possible to that used for haploids. Let us now consider an infinite population of haploids, or diploids without dominance, which experience mutation and selection, but no recombination. In our study, chromosome gain was only apparent in the haploid strains. In order to test for ' dominance ', crosses were made between haploids derived from a single heterozygous mutant strain.
