In plants, twisted leaves, a hypothetical mutant phenotype, maybe caused by either a chloroplast gene (CT =normal; Ct = twisted) or a recessive nucleargene (NT = normal; Nt =twisted). Assume chloroplast DNA is maternally inherited. Predictthe genotypic and phenotypic ratios in the offspring of thefollowing crosses:
a.        CT NtNt female xCt NTNT male
b.        Ct NtNt female xCT NTNT male
c.        F1 male from cross (a) x F1female from cross (b)
