  2. Sister chromatids - Wikipedia

    en.wikipedia.org/wiki/Sister_chromatids

    The paternal (blue) chromosome and the maternal (pink) chromosome are homologous chromosomes. Following chromosomal DNA replication, the blue chromosome is composed of two identical sister chromatids and the pink chromosome is composed of two identical sister chromatids. In mitosis, the sister chromatids separate into the daughter cells, but ...

  3. Chromatid - Wikipedia

    en.wikipedia.org/wiki/Chromatid

    During cell division, the identical copies (called a "sister chromatid pair") are joined at the region called the centromere (2). Once the paired sister chromatids have separated from one another (in the anaphase of mitosis) each is known as a daughter chromosome. The short arm of the right chromatid (3), and the long arm of the right chromatid ...

    en.wikipedia.org/wiki/Chromosome_3

    Chromosome 3 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. People normally have two copies of this chromosome. Chromosome 3 spans more than 198 million base pairs (the building material of DNA ) and represents about 6.5 percent of the total DNA in cells .

  7. Homologous chromosome - Wikipedia

    en.wikipedia.org/wiki/Homologous_chromosome

    After mitosis occurs within the daughter cells, they have the correct number of genes which are a mix of the two parents' genes. In diploid (2n) organisms, the genome is composed of one set of each homologous chromosome pair, as compared to tetraploid organisms which may have two sets of each homologous chromosome pair.

  8. Chromosomal crossover - Wikipedia

    en.wikipedia.org/wiki/Chromosomal_crossover

    If two genes are located close together on a chromosome, the likelihood that a recombination event will separate these two genes is less than if they were farther apart. Genetic linkage describes the tendency of genes to be inherited together as a result of their location on the same chromosome.

  9. Chromosome regions - Wikipedia

    en.wikipedia.org/wiki/Chromosome_regions

    If the chromosome is a submetacentric chromosome (One arm big and the other arm small) then the centromere divides each chromosome into two regions: the smaller one, which is the p region, and the bigger one, the q region. The sister chromatids will be distributed to each daughter cell at the end of the cell division.
