How is karyotyping related to meiosis
WebA karyotype is the number and appearance of chromosomes, and includes their length, banding pattern, and centromere position. To obtain a view of an individual’s karyotype, cytologists photograph the chromosomes and then cut and paste each chromosome into a chart, or karyogram, also known as an ideogram (Figure 1). Figure 1. WebA karyotype test looks for unusual changes in chromosomes.
