The cross between Dd egg-snail and a dd s snail mate will result in snails with genotype 1/2 Dd:1/2 dd and phenotype all right-coiling.
<h3>What is a genotype?</h3>
The genotype refers to the allele combinations that can be found for one or more loci in an individual.
The phenotype refers to how the genes and alleles interact to produce a physical trait in an organism.
In this case, one parent can produce two types of gametes (D and d), whereas the other parent can only produce d gametes.
