Gene linkage means:
Correct answer: D. Linkage of a gene with a particular gene
- A. Linkage of a gene with male
- B. Linkage of a gene with female
- C. Linkage of a gene with particular gender
- D. Linkage of a gene with a particular gene
Explanation
Gene linkage refers to the phenomenon where two or more genes are located close to each other on the same chromosome and tend to be inherited together as a unit. In other words, linked genes are physically close to each other on the same chromosome, and they are usually inherited as a package rather than independently assorting during meiosis. All genes located on the same chromosomes are linked to each other. This phenomenon of staying together is called linkage.

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.
