Amaternal effect can cause the offspring phenotype ratio to depart from that of classic mendelian inheritance. in a species of snail, the dominant allele n codes for right-handed shell coiling and recessive allele n codes for left-handed shell coiling. if an nn female with right-handed shell coiling mates with an nn male, what is the shell coiling phenotypic ratio of their offspring?
