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?
