Maternal inheritance of coiling of shell in snail (limnaea peregra) is well established. The dextral coiling depends on dominant allele D and sinistral coiling depends upon recessive allele d. A female F1 progeny of dextral(Dd) type is crossed with a male dextral (Dd). What will be the phenotype ratio in progeny?

In the plants, due to mutation in the mitochondrial genome causing cytoplasmic male sterility can be influenced by the nuclear gene (Rf), which is dominant over the cytoplasmic mitochondrial genome. If a male sterile plant is pollinated by the fertile male plant with homozygous (Rf)condition, the progeny obtained in F1 will have
