Two genes on the same chromosome that lie very far apart will show
Correct answer: C. a higher recombination frequency than genes lying close together
- A. no recombination at all
- B. complete linkage in every meiosis
- C. a higher recombination frequency than genes lying close together
- D. fewer crossing overs than genes lying close together
Explanation
The longer the stretch of chromosome between two genes, the more likely a crossover will fall between them, so distant genes recombine more often. Genes very close together are strongly linked and rarely separated.

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
