There are organisms that go through meiosis but do not undergo recombination when forming haploid gametes. Which of the following statements correctly describes the gametes produced by such an organism? (Assume that these organisms are diploid, that each of the two homologous chromosomes are genetically distinct as typically found in the wild, and that these organisms have more than one chromosome.)

a. All gametes formed during a single meiosis will be identical.

b. Due to the random assortment of homologs, each of the gametes formed during a single meiosis will be different.

c. This organism could potentially produce 2n genetically distinct gametes, where n is its haploid number of chromosomes.

d. The fusion of any two gametes produced by such an organism that does not undergo recombination during meiosis will create a cell that is genetically identical to that individual.

Expert Solution

a. All gametes formed during a single meiosis will be identical - False
        Chromosomes are segregated randomly. We cannot predict which one will segregate to which cell. There are multiple-choice for the combinations of chromosomes present in each daughter cells

b. Due to the random assortment of homologs, each of the gametes formed during a single meiosis will be different - True
         Each gamete will differ due to the random assortment of distinct homologous chromosomes to daughter cells

c. This organism could potentially produce 2n genetically distinct gametes, where n is its haploid number of chromosomes - false
       This organism is undergoing meiosis even though there is no recombination. Meiosis can result in haploid gametes without recombination also

d. The fusion of any two gametes produced by such an organism that does not undergo recombination during meiosis will create a cell that is genetically identical to that individual - false
          Each gamete is a different due random assortment of chromosomes. So the fusion of any of these gametes will not produce genetically identical cells to that of parents.

Most mammalian cell types do not undergo homologous recombination (HR), and even mouse ES cells do so at low frequency - about 1/200000 cells. However, if you first introduce a crRNA designed to target a mouse genomic sequence next to a PAM site, plus a source of Cas9 protein and a plasmid with homology arms, most mouse cell types will undergo HR with very high frequency -as high as 1/5 or more of the treated cells. What does this tell...
