Option B
Option C
Option D
Solution
| Crossing over | Linkage |
| $(1)$ It leads to separation of linked genes. | $(1)$ Keeps the genes together. |
| $(2)$ It involves exchange of segments between non sister chromatids of homologous chromosomes. | $(2)$ It involves individual chromosomes. |
| $(3)$ The frequency of crossing over can never exceed $50 \%$. | $(3)$ The number of linkage group can never be more than haploid chromosome number. |
| $(4)$ It increases variability by forming new gene combinations. | $(4)$ It reduces variability. |
