Some snail species' shells can have right-handed direction of shell coiling or left-handed direction of shell coiling. The direc

tion of coiling depends on a protein deposited by the mother in the egg cytoplasm with DD and Dd mothers depositing a protein that directs right-handed direction of coiling in shells. If Dd egg-producing snail and a dd sperm-producing snail mate what genotype(s) and phenotype(s) of offspring will result

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.

Sun-centered Solar System was theorized by Copernicus. The paths assumed to be relatively circular (or elliptical).
