In a genetic map, chromosomal aberration changes the order of the genes but does not change the linkage group. This is because:
- a)translocation
- b)recombination
- c)transposition
- d)inversion
Correct answer is option 'D'. Can you explain this answer?

In a genetic map, chromosomal aberration changes the order of the gene...
Concept:
- Over a long period of time, a species chromosomal set is largely stable.
- However, chromosomal anomalies, either in terms of number or structure, can occur within populations.
- These changes come about on their own as a result of mistakes in the cell regular functions.
- In most circumstances, their effects are negative, leading to the birth of unwell or infertile people, but in a few rare instances, modifications offer fresh opportunities for adaptation that enable evolutionary change to take place.
- In reality, it is now widely accepted that drastic reorganisation of chromosome design has played a significant role in evolution as a result of the discovery of distinguishable chromosomal changes between species.
Explanation:
- Deletion, Duplication, Translocation and Inversion are some different types of Chromosomal anomalies.
- Linkage group describes the variety of chromosomes that each species has.
- One X and one Y linkage group are among the human race's 22 autosomal linkage groups.
- Rearrangement of a chromosomal segment between two non-homologous chromosomes, or translocation (moving a gene from one linkage group to another), is not a normal aspect of the cell cycle and happens as a result of an induced defect.
- Inversion and duplication cause rearrangement of genes on same chromosome thus there is a change in the order of genes within the same linkage group.
- Genes are exchanged between two homologous chromosomes as a result of crossing over. a recombination-producing process that takes place during meiosis I.
hence the correct answer is option 4

In a genetic map, chromosomal aberration changes the order of the gene...
Explanation:
Chromosomal aberration:
Chromosomal aberration refers to any change in the normal structure or number of chromosomes in an organism.
Genetic map:
A genetic map is a representation of the arrangement of genes on a chromosome.
Changes in the order of genes:
Chromosomal aberrations such as inversions can cause changes in the order of genes on a chromosome. In an inversion, a segment of the chromosome breaks off, flips around, and reattaches itself in the opposite orientation.
Linkage group:
A linkage group is a set of genes that are inherited together because they are located close to each other on the same chromosome.
Effect of inversion on genetic map:
- Inversion changes the order of genes on a chromosome but does not change the linkage group.
- This is because the genes involved in the inversion are still physically close to each other on the chromosome.
- As a result, these genes are still inherited together and exhibit linkage, despite their new order.
Therefore, in a genetic map, chromosomal aberration such as inversion can change the order of genes but does not change the linkage group.
