Analysis of Tetrads from the yeast Saccaromyces
... When normally haploid yeast cells of two different mating types encounter each other, they fuse to form a diploid zygote (this constitutes a cross), which immediately undergoes meiosis to regenerate four individual haploid spores – a tetrad (the equivalent of an F1 generation). Since each meiotic te ...
