Question
Meiosis is of evolutionary significance as it produces
Hint:
Meiosis is of evolutionary significance as it produces tetrad.
The correct answer is: Four daughter cells
Meiosis cuts the cell's chromosome number in half while creating new allelic combinations through segregation and recombination to distribute to the four daughter cells. This gene rearrangement reduces gene association within and between loci and is thought to be the basis for successful sexual reproduction.
