How is a chromosome in which the centromere is near the middle called?

• Submetacentric

• Telocentric

• Metacentric

• Acrocentric

How would you call a process when a normal chromosome has broken into two separate pieces and the piece of the chromosome without the centromere is lost and degraded?

• Duplication

• Reciprocal translocation

• Segmental duplication

• Terminal deletion

How would you name the inverted region when the centromere is found outside the inverted region?

• Pericentric inversion
