male sterility in maize

Post by geneticsquest » Mon Jul 12, 2010 5:43 pm

which cross will produce all male-sterile progeny?
(In each genotype, the mitochondrial genotype is designated as ms or mf and the homozygous nuclear genotypes as RR or rr. The female parent in each cross is listed first).

A) ms; rr x mf; RR
B) ms; RR x mf; rr rr
C) ms; rr; x ms; RR
D) ms; rr x mf; rr
E) ms; rr x ms

* initially I chose E, but now i'm not sure..i'm now also thinking of D
Anyone have any advice??

what are R/r? Is it related to the male sterility?

I would say D

Cis or trans? That's what matters.
