Crossing over in diploid organism is responsible for:
Correct answer: B. Recombination of linked alleles
- A. Segregation of alleles
- B. Recombination of linked alleles
- C. Dominance of genes
- D. Linkage between genes
Explanation
Crossing over in diploid organisms is a fundamental mechanism that enables the recombination of linked alleles. During this process, genetic material is exchanged between homologous chromosomes, creating new combinations of alleles and contributing to genetic diversity in a population. This recombination plays a crucial role in breaking up linkage between genes on the same chromosome and maintaining genetic variability.

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.
