The movement of a gene from one linkage group to another is called:
Correct answer: A. Translocation
- A. Translocation
- B. Crossing over
- C. Inversion
- D. Duplication
Explanation
The correct answer is Translocation. This chromosomal abnormality involves the rearrangement of genetic material between non-homologous chromosomes, which can result in a gene moving from one linkage group to another. Other options, such as Crossing over, involve genetic exchanges within homologous chromosomes and do not lead to linkage group changes. Inversion and Duplication alter the structure or number of genes on a chromosome but do not change linkage groups.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
