Which situation can reduce the chances of variation and genetic recombination?
Correct answer: C. Gene linkage
- A. Random fusion of gametes
- B. Crossing over
- C. Gene linkage
- D. Mutation
Explanation
Gene linkage does not obey Mendel's law of independent assortment. Hence the chances of variation and genetic recombination are reduced.

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.
