#Unit 8. Inheritance Biology

Deletion of a number of pairs that is not evenly divisible by three will lead to a frameshift mutation.

#Unit 8. Inheritance Biology

In an individual heterozygous for a deletion, the normal chromosome loops out during chromosome pairing in prophase I.

#Unit 8. Inheritance Biology

Deletion includes the centromere, then the chromosome will not segregate in meiosis or mitosis and will usually be lost.

Deletions are lethal in the homozygous state because all copies of any essential genes located in the deleted region are missing.
