What is a karyotype?

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Definition of Karyotype**: A karyotype is defined as the general appearance of chromosomes in an organism. It provides a visual representation of the number, size, shape, and arrangement of chromosomes. 2. **Preparation of Karyotype**: Karyotypes are prepared using cells that are in the metaphase stage of cell division. During metaphase, chromosomes are highly condensed and coiled, making them easier to observe. 3. **Chromosomal Duplication**: At this stage, the chromosomal strands have duplicated, meaning each chromosome consists of two identical sister chromatids. This duplication is crucial for the accurate separation of chromosomes during cell division. ...
