In Chlamydomonas, you cross two cells with the genotypes (smS mt+) × (smR mt-). What ratio would you expect in the offspring with respect to both the nuclear and choloroplast genes?

2:2 ratio (smS mt+):(smS mt-)

  

1:1:1:1 ratio (smS mt+):(smS mt-):(smR mt+):(smR mt-)

  

2:2 ratio of (smS mt+):(smR mt+)

  

3:1 ratio (smS mt+):(smR mt+)
