How do parents and daughters cells differ genetically in meiosis?

Answer 1

In mitosis the two daughter cells and the parent cell are so genetically similar for many reasons. One reason that this is true is that in mitosis cells only divide once, so each cell gets half of the mother cells genes or chromosomes. This means that the daughter cells are alike because they are both getting all of their chromosomes (haploid number) from the same mother cell and they are like the mother cell because they are getting their genes from that cell.

Answer 2

Since meiosis results in cells with only half the DNA of normal cells (because they are sex cells) then the genetic makeup will be different in each of the 4 daughter cells and different from that of their parent cell.

Answer 3

In meiosis, parent cells are diploid, containing a full set of DNA (in humans, 23 pairs of chromosomes - 46 all together). Daughter cells are haploid, containing one half of each chromosome pair (in humans, 23 chromosomes).

Answer 4

During prophase I of meiosis crossing over of homologous chromosomes occurs. This results in recombined DNA in which each chromatid is a combination of the DNA from both parents. Because of this, the daughter cells resulting from meiosis are non-identical to each other and the parent cell. They are also haploid, while the parent cell is diploid.

Answer 5

During meiosis, parents and daughter cells differ genetically because meiosis involves two rounds of cell division resulting in the halving of the genetic material. Parent cells are diploid (2n) and give rise to haploid (n) daughter cells with genetic variability due to crossing over and independent assortment. This leads to the creation of genetically unique daughter cells with a different combination of alleles than the parent cells.
