1. new individual formed by fusion of two gametes. a. gamete has one-half (haploid) number of chromosomes b. gametes (sperm and ova) formed by meiosis 2. Fertilization a. combination of male and female gametes, each with one of each pair of homologous chromosomes ...
But unlike animals, the plant parents make pairs of gametes (sex cells) instead of just one each--in the ovule there is one egg cell and one "central cell," while in the pollen grains, there are two sperm. To catch a clone: a new use of laser technology identifies clones among flowe...
1.The cell formed by the union of two gametes, especially a fertilized ovum before cleavage. 2.The organism that develops from a zygote. zy·got′ic(-gŏt′ĭk)adj. zy·got′i·cal·lyadv. The American Heritage® Medical Dictionary Copyright © 2007, 2004 by Houghton Mifflin Company...
This is similar to that of mitosis except for the fact that in meiosis, it is followed by two cell divisions. Prophase 1 Chromosomes condense and attach to the nuclear envelope. Synapsis then takes place and tetrads are formed, each composed of four chromatids. Crossing over of genetic mater...
during anaphasethe homologues separate with their individual sister chromatids joined together and move to opposite poles to generate two cells. Each cell so formed has one of the homologues. These cells from meiosis I proceed to meiosis II, which is similar to mitosis. The two sister chromatid...
For the first time, we demonstrate that the DNA sequences originating from a single sub-nuclear structure in a single cell targeted by two-photon irradiation can be determined, and mapped to a particular locus. Its application to single PML nuclear bodies reveals ontologically related loci that ...
A cell formed by cell division. decoy cell decoy cell decoy cell A cell found in the urine with inclusion bodies in its nucleus. It indicates infection in renal transplant recipients. delta cell delta cell delta cell SEE: D cell. dendritic cell dendritic cell dendritic cell An antigen-presen...
This results in two groups of monovalent chromosomes.Telophase - At the end of anaphase, another stage starts where nuclear membranes start to form around the two formed groups of chromosomes. The spindle fibers that attached to the chromatids get disassembled. Here, the chromosomes also condense....

4.Telophase I:the chromosomes reach the poles. Nucleolus and nuclear membrane reappear. It produces two daughter cells each containing a single nucleus. Cytokinesis:two daughter cells are formed which are haploid. Interkinesis:metabolic stage between telophase I and prophase II. Chromosomes elongate d...
