Which of the following will not result in variations among siblings?
Correct answer: D. Linkage
- A. Independent assortment of genes
- B. Mutation
- C. Crossing over
- D. Linkage
Explanation
1. In terms of genetics and genomics, linkage describes how closely genes or other DNA sequences are located to one another on the same chromosome. 2. The likelihood that two genes or sequences will be inherited together increases with their proximity on a chromosome. 3. Numerous factors, including selection, the rate of genetic recombination, mutation rate, genetic drift, the mating system, population structure, and genetic linkage, all have an impact on linkage disequilibrium

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.
