Assorted Mixed
In which ways does meiosis produce genetic diversity?
a) “Crossing-over” of genes between different (homologous) chromosomes mixes up the DNA sequences on each chromosome
b) The chromosomes “independently assort” into daughter cells randomly
c) The daughter cells only have one copy of each chromosome
A & B
B & C
A is correct, there is homologous recombination between different copies of the same chromosome, leading to slight changes from one to the next.
B is also correct, there is no selection process for the assortment of chromosomes.
C is not correct. When speaking of yeast, as the haploid cells (containing only one copy of each chromosome) grow and divide anything that damages a copy of a gene may damage the cell because they do not have a backup copy. And since the haploid cannot divide through meiosis, you lose the effects of A & B.
