Crossing Autosomal Gene Explain Disrupts Linkage Occasionally Linked

Crossing over disrupts autosomal linkage between genes when they are far apart on the chromosome. The greater the distance, the higher the probability of a crossover event occurring between them, leading to new allele combinations in the gametes.

La recombinación genética puede romper el vínculo autosómico entre genes cuando estos están físicamente distantes en el cromosoma, ya que la probabilidad de que ocurra un entrecruzamiento entre ellos aumenta, permitiendo la formación de nuevas combinaciones de alelos.

Front Explain why crossing over disrupts autosomal linkage, but only occasionally.
Back Crossing over & autosomal linkage:
  • If two genes are linked but are far apart, they are likely to be separated during crossing over
  • This is becasue any gene loci below point of breaking during crossing over will be exchanged as a result of recombination, creating new gene combinations
  • This allows every gamete combination to form
