why crossing over occurs only between homologous pair

Answers

Answered by Anonymous

Answer:

Explanation:Crossing over occurs between homologous chromosomes as they share the genes responsible for the same character, i.e one gene is responsible for one trait while the other gene is responsible for the other trait, but for the same character. ... On the other hand non-homologous chromosomes carry all-together different genes.

Answered by priyanshi717

Answer:

During this lining up, DNA sequences can be exchanged between the homologous chromosomes. This type of genetic recombination is called crossing over, and allows the daughter cells of meiosis to be genetically unique from one another. Crossing over can only occur between homologous chromosomes.
