What does effective homolog linkage depend on?
Homolog linkage:
Homolog linkage:
However, the Law of Independent Assortment is applicable for the genes that are present on different chromosomes that aren't in the proximity of one another. Effective homolog relation depends on the positioning of chiasmata along the chromosomes.
still, also the small quantum of arm cohesion distal to that chiasma may not be sufficient to hold the homologs together before metaphase, and crimes in isolation may do, If homologs are linked by a single chiasma that's veritably close to the end of the chromosome.
On the other side, a single chiasma that's in propinquity to the centromere may not be effectively resolved in meiosis I because family- chromatid cohesion is maintained near the centromere until meiosis II.
For similar causes, near the centromeres and telomeres, the crossover conformation is suppressed.
