<h2>Answer:</h2>
If the crossover results in the pair of the chromosome, in which one contains no mutant allele while others contain two mutant alleles.
<h3>Explanation:</h3>
- The crossing over is the genetic random recombination phenomenon in the meiosis.
- In meiosis two homologous chromosomes randomly exchange their genetic material.
- This genetic exchange can be that much random that any part of one chromosome which is near to other can be exchanged leading to lethal and beneficial mutations.
- In crossing over if one chromosome gets the mutant part of the second chromosome while other chromosome gets the normal genetic material in return. This leads to one normal chromosome and the second chromosome having two mutant alleles.
Ependyma cells. These cells
that make up the neuroectodermal padding is responsible for the production of cerebral
spinal fluid. The cells are one type of neuroglia
cells of the central nervous system. The lining of ependyma cells of the brain also
plays a role in neuroregeneration.
