In snail shells the direction of shell coiling is controlled by a maternal effect gene. Two alleles, a dominant one, D, causes dextral (right handed) coiling, and a recessive one, d, causing sinistral (left hand) coiling.
Given three different female snails of genotypes DD, Dd, and dd, crossed with dd males.
What are the phenotypes of the offspring of each
DD females:
Dd females:
dd females:
What are the phenotypes of these females. Explain, based on the probable parental (both maternal and paternal for each female. (Hint: you may not be able to give definitive answers for each. If so explain why in terms of the possible parents.)
