How are chromosomes arranged
Webchromosomes that are the same size, shape, and carry genes for the same traits homologues cells that only have one of each chromosome and no homologous pairs, haploid, "gametes" sex cells a picture of the chromosomes in which the chromosomes arranged in matching homologous pairs karyotype WebAt the end of metaphase, the chromosomes are lined up along the metaphase plate, an imaginary plane in the middle of the cell. Following metaphase, anaphaseoccurs. At the beginning of anaphase, the centromeres holding sister chromatids together will split and will be pulled apart to create independent chromosomes.

WebA karyotype is an image showing all of the chromosomes in a cell. They are normally used to help diagnose specific genetic conditions, such as Trisomy 21. Trisomy 21, more commonly known as Down Syndrome, is a condition in which an individual has an extra copy of chromosome 21. WebIn karyotyping chromosomes are arranged in pairs (homologous pairs) according to size (length) and structure (location of centromeres and banding pattern).
