If the synaptonemal complex cannot be cleaved during Meiosis I, what will happen to the homologous chromosomes?
Understand the Problem
The question is asking about the consequences if the synaptonemal complex cannot be cleaved during Meiosis I, specifically focusing on the behavior of homologous chromosomes.
Answer
The homologous chromosomes won't separate properly, causing meiotic arrest or segregation defects.
If the synaptonemal complex cannot be cleaved during Meiosis I, the homologous chromosomes would not be able to separate properly, leading to a meiotic arrest or defects in chromosome segregation.
Answer for screen readers
If the synaptonemal complex cannot be cleaved during Meiosis I, the homologous chromosomes would not be able to separate properly, leading to a meiotic arrest or defects in chromosome segregation.
More Information
The synaptonemal complex is essential for the proper pairing and segregation of homologous chromosomes during Meiosis I. Its cleavage allows homologous chromosomes to be separated and distributed into daughter cells.
Tips
A common mistake is misunderstanding the role of the synaptonemal complex only in the chromosome pairing, whereas it is also crucial for their subsequent separation.
