Answer
To complete a karyotype, you need to match homologous chromosomes based on size, banding pattern, and centromere position using figures from your textbook.
Solution
a
Identify all chromosomes: Use the figures in your textbook to identify all 23 pairs of chromosomes, including the sex chromosomes (XX for females and XY for males)
b
Arrange chromosomes: Arrange the chromosomes in pairs from largest to smallest, with the sex chromosomes being the last pair
c
Match homologous pairs: Match each chromosome with its homologous partner based on size, banding pattern, and centromere position
d
Organize karyotype: Organize the matched pairs in a layout, typically with the shorter arm (p) on top and the longer arm (q) on the bottom
Key Concept
Karyotyping is the process of pairing and ordering all the chromosomes of an organism, providing a visual profile of its chromosomal makeup.
Explanation
By comparing the chromosomes' physical characteristics, such as size and banding patterns, you can arrange them into a karyotype for analysis. This is often used to detect chromosomal abnormalities.
