Shell coiling in snail is determined by genetic maternal effect for a single loci having D allele for dextral coiling but S allele for sinistral coiling. D dominant over S. which of the following cross would produced all progeny that is dextral coiling ?
I- DD Male X SS female
II- DD Male X DS female
III- SS Male X DD female
IV - DS Male X DS female

following cross were allowed
I-Recessive phenotype female X Dominat phenotype male = all recessive phenotype
II-Recessive phenotype male X Dominat phenotype female = all dominant phenotype
Which of the following conclusion?

A certain kind of snail can have a right-handed direction of shell coiling (D) or left handed coiling (d). If direction of coiling is due to a protein deposited by the mother in the egg cytoplasm, then a Dd egg-producing snail and a dd sperm-producing snail will have offspring of which genotype(s) and phenotype(s)?

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?
