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.

by an abnormal reaction to a harmless antigen in the environment. These
diseases include food allergies, hay fever, atopic dermatitis and allergic
asthma. Symptoms may include, a runny nose, shortness of breath, swelling red

hypersensitivity.
Answer:
Frameshifts are caused by the addition or deletion of a nucleotide in the DNA sequence. It does not occur if there are three deletions or additions simultaneously (because codons are 3 nucleotides long). A frameshift mutation will cause the reading of the codons after the mutation to code for different amino acids. It also alters where the "stop" codons are located.
