Based on the Karyotype shown, at which chromosome pair can we identify a genetic disorder? 

• 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)

A pair of identical chromosomes shown in a karyotype, one inherited from mom, and one inherited from dad are called

• sister chromotids
• centromeres
• homologous chromosomes
• autosomes
