• Chromosome pair 5
• sex chromosomes
• Chromosome pair 21
• There are no chromosomal disorders

What is the chromosomal condition of the individual whose karyotype is seen in the image?

• Monosomy X (Turner's Syndrome)
• Trisomy 21 (Down's Syndrome)
• Trisomy 13 (Patau Syndrome)
• Trisomy 18 (Edwards's Syndrome)

Which statement is NOT true about Karyotypes

• Chromosomes (pairs 1-22) are arranged by size
• Sex chromosomes are found at the end
• A normal karyotype has 46 chromosomes or 23 pairs
• Having missing or extra chromosomes does not indicate a disorder

A pair of identical chromosomes shown in a karyotype, one inherited from the female, and one inherited from the male are called

• sister chromotids

• centromeres

• homologous chromosomes

• autosomes
