1 Ιουν 2024 · Definition of Deletion Mutation. A deletion mutation is a genetic anomaly in which a segment of a chromosome or DNA sequence is omitted during DNA replication, leading to the absence of specific nucleotides or entire chromosomal segments. This can result in altered gene function or expression.
24 Απρ 2023 · Genetic disorders traditionally fall into three main categories: single-gene defects, chromosomal abnormalities, and multifactorial conditions. A chromosomal abnormality, or chromosomal aberration, is a disorder characterized by a morphological or numerical alteration in single or multiple chromosomes, affecting autosomes, sex chromosomes, or both.
Chromosomal Mutations • Chromosome structure • Variation in Chromosome structure • Duplication • Deletions • Inversions • Translocations • Change in Chromosome number and sets
Chromosomal Deletions. Figure 3. Figure Detail. Deletions involve the loss of DNA sequences. Phenotypic effects of deletions depend on the size and location of deleted sequences on the genome....

In genetics, a deletion (also called gene deletion, deficiency, or deletion mutation) (sign: Δ) is a mutation (a genetic aberration) in which a part of a chromosome or a sequence of DNA is left out during DNA replication.
