Shell coiling of the snail Limnaea peregra(genetic maternal effect)  the shell coils (s+s+) which is termed dextral coiling, while some snails exhibiting sinistral coiling (ss). The allele for dextral (s +) is dominant over the allele for sinistral (s). If a male homozygous for dextral alleles (s+s+) is crossed with a female homozygous for sinistral alleles (ss) all of the F1 are heterozygous (s+s) and have a sinistral shell. If these F1 snails are self-fertilized, what is the phenotype of the F2 snail?
