| Question | Answer |
|---|---|
| Centriole | A barrel-shaped structure that has a role in microtubule formation in cilia, flagella, and eukaryotic spindles. |
| Haploid | Having one of each type of chromosome characteristic of the species.(Human gamete is haploid) (배우자, 생식세포-gamete) |
| Sister chromatid | One of two attached members of a duplicated eukaryotic chromosome. |
| Centromere | Constricted region in a eukaryotic chromosome where sister chromatids are attached. |
| Cleavage furrow | Aring of Actin filaments begin to contract at equator. |
| Cell plate formation | Microtubules & Actin filaments use in mitosis determine plane of division. |
| Diploid | Having two of each type of chromsome characteristic of the species. |
| Zygote | Cell formed by fusion of gametes ; first cell of a new individual. |
| Crossing over | Process in which homologous chromosomes exchange corresponding segments during prophase I of meiosis. (put onoparental combinations of alleles in gemete.) |
| Homologous chromosome | one of a pair of chromosomes in body cells of diploid organisms.(same length, shape, genes) |
| sex cell(Gamete) | Mature, Haploid reproductive cell.(egg or sperm) |
| Spores | A dominant, reproductive cell formed by certain organisms. |
| True breeding | A kind of breeding in which the parents with a particular phenotype produce offspring only with the same phenotype. |
| probability | Chance that a particular outcome of an event will occur; depends on the total number of outcomes possible. |
| P generation | The first set of parents crossed in which their genotype is the basis for predicting the genotype of their offspring, which in turn, may be crossed. |
| F1 Generation | The first filial generation, which is comprised of offspring resulting from a cross between stains or distinct genotype |
| F2 generation | The second filial generation, which is comprised of offspring(s) resulting from a cross of the members of F1 generation |
| Genotype | The particular alleles carried by an individual. |
| Phenotype | An individual's observable traits. |
| Karyotype | Image of an individual's complement of chromosomes arranged by size, length, shape, and centromere location. |
| Autosome | Any chromosome other than a sex chromosome. |
| Sex chromosome | Member of a pair of chromosomes that differs between males, and females. |
| Pedigree | Chart showing the pattern od inheritance of a gene in a family. |
| Recessive | With regards to an alleles, having effects that are masked by a dominant allele on the homologous chromosome. |
| Spindle fibers | Any of a network of filaments that collectively form a mitotic spindle (in mitosis) and meiotic spindle (in meiosis). It is chiefly involved in moving and segregating the chromosomes during nuclear division. |
| Heterozygous | Having two different alleles at a gene locus; Aa |
| Chromatin | loose uncoiled DNA |
| Chromosome | coiled(single) |
| Chromatid | Attached |
| Apoptosis | Nutural cell death |
