Question

Genetics help pretty please!

Three haploid yeast petite mutants were isolated, one from each of the three classes of petite mutations--suppressive petites, neutral petites, and segregational petites. You perform the crosses shown in this table. Several isolated haploid petite mutants and wild-type cells were mated with each other on complete media to form diploid cells. The diploid cells were then starved so they would go through meiosis and form haploid spores. The spores were grown on minimal media plates that contained glycerol as the only carbon source (so no fermentation could occur). Which of the following diploid cells would be able to produce haploid spores that could grow on the minimal media plus glycerol plates? Select all that apply. segregational petite/wild type segregational petite/neutral petite segregational petite/suppressive petite suppressive petite/wild type suppressive petite/neutral petite neutral petite/wild type

Explanation / Answer

Segregational pettie with wild type produce haploid spores. Segregational pettite and wild type cells were mated with each other on neutral media to form haploid spores. The diploid cells are starved and it can undergo meiosis and form haploid spores. Segregational pettite with wild type cells are failed to produce haploid spores and the growth is suppressed. Neutral pettie with wild type also do not produce haploid spores.
