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

Approximately 50% of the meiotic products from the rec12-117 and rec12-D15 (null) mutants were inviable (Figure 4A), indicating that about 50% of the products were nullisomic for one or more chromosomes.
Since S. pombe contains only three chromosome pairs, aberrant assortment during one or both of the meiotic divisions can produce, by chance, a significant fraction of meiotic products that receive at least one copy of each chromosome and are hence viable [ 38 43 ] . Aberrant segregation can also produce nullisomic aneuploids (missing one or more chromosomes), polysomic aneuploids (having additional copies of individual chromosomes), and diploids [ 38 39 44 ] . In S. pombe the haploids and diploids are viable, nullisomic aneuploids are inviable, and disomic aneuploids tend to lose the extra chromosome or chromosomes and become haploid [ 45 ] . We therefore determined the frequencies of spore viability and meiotic diploidy as genetic measures of chromosome segregation errors.
