Cytological basis of crossing over biology discussion
Answers
Answer:
Cytological basis of crossing over. ... Crossing Over. • Crossing over is a process that produces new combinations of genes by exchanging segments between non-sister chromatids of homologous chromosomes normally reciprocally but sometimes unequally.
Explanation:
Answer:
The cytological basis of crossing over occurs in all meiotic cells of bisexual reproduction. There are two divisions of meiosis as meiosis-I and Meiosis-II.
The crossing over enables refurbishing the genetic material to be passed to the next generation through sexual gametes that form at the end of Meiosis-II division.
Morgan and his collaborators established the genetic basis of crossing over and linkage describing the exchange of parts between the homologous chromosomes and linear arrangement of linked genes along chromosomes.
