Chromosomal Mutations

Question 1

Affects either the chromosome’s structure or its number

Answer 1

Chromosomal Mutations

Question 2

Changes the structure of the chromosome and genes that can occur spontaneously

Answer 2

Structural Mutations

Question 3

a part in the chromosome or sequence of DNA is left out during the DNA replication

Answer 3

Chromosome Deletion

Question 4

• an extra copy of segment of chromosome
• A person with a duplication has three copies of a particular chromosome

Answer 4

Chromosome Duplication

Question 5

occurs when a chromosome breaks and the (typically two) fragmented pieces re-attach to different chromosomes

Answer 5

Chromosome Translocation

Question 6

Two different chromosome have exchange segments

Answer 6

Reciprocal Translocation

Question 7

Certain type of chromosome is attached to other.

Answer 7

Robertsonian Translocation

Question 8

• the chromosome segment is rearranged and is reversed.
• Single chromosome undergoes breakage and rearrangement within itself

Answer 8

Chromosome Inversion

Question 9

• Normal chromosome has one long arm q and one short arm p
• An isochrome has two longs arms and two short arms
• It results to extra or missing genes

Answer 9

Isochrome

Question 10

• Circular structure that occurs when chromosome breaks in two places and ends fuse together
• This is caused by deletion in both arms of chromosomes and this will result in missing DNA

Answer 10

Chromosome Rings

Question 11

A person has a missing copy of a chromosome, resulting in only one copy of that chromosome.

Answer 11

Monosomy

Question 12

A person has an extra copy of a chromosome, resulting in three copies of that chromosome.

Answer 12

Trisomy

Question 13

is a type of genetic testing observing the numbers, size, shape, and sex.

Answer 13

Karyotype test
