How can you use “tetrads” in a sentence? Here are some example sentences to help you improve your vocabulary:

We then sporulated the heterozygotes, dissected tetrads, and scored for spore viability and the presence of the kanMX marker.
Haploid segregants from three complete tetrads were cultured for 24, 48 and 72 hours in SDC medium, lysed, and levels of ApppN and AppppN were determined.
An earlier report demonstrated that disruption of HNT2 was tolerated by haploid yeast strains without an effect on growth and that ApppN and AppppN accumulate 30 and 3-fold, respectively on account of the hnt2 deletion [ 13 ] . Because those data were obtained by random spore analysis, we considered it important to test whether elevated dinucleoside polyphosphate levels co-segregate with hnt2 disruption in all tetrads examined and whether any other commonly used genetic markers affect dinucleoside polyphosphate levels.
The resultant MDN1(HA)/MDN1 diploid strain was sporulated and the tetrads dissected.
We found for both knock-outs that 20 out of 20 tetrads yielded only 2 viable spores and all of the viable haploids were G418-sensitive, i.e., none contained the pct1::kanMX or pce1::kanMX alleles.
