Mating in Chlamydomonas Occurs Between Haploid Mt+ and Mt- Individuals

question 49

Short Answer

Mating in Chlamydomonas occurs between haploid mt+ and mt- individuals. The mt- chloroplast genome is selectively degraded 95% of the time. In one such mating, the mt+ genome is strR and mt- is strS. Will offspring live or die if they are exposed to streptomycin?
