As of today I am conducting an experiment with Neocaridina heteropoda. I am going to attempt to describe the genetics of the red coloration found in the Cherry Red Shrimp (Neocaridina heteropoda var. Red). I will be crossing the wild type and the red verity of the Neocaridina heteropoda and then crossing the F1 offspring with the red variant and themselves.

This experiment should show weather the Red gene is a recessive, a double recessive, or another type. I do not believe the gene is sex linked, and do believe it to be a double recessive. Here is the experiment as I plan to conduct it.

Characterization:

What are the genetics of the red coloration of a Cherry Red Shrimp?

Hypothesis:

The Red gene is a double recessive non-sex linked gene.

Predictions:

- Fry of Male Red and Female Wild will all be wild colored. (F1)

- Fry of Female Red and Male Wild will all be wild colored. (F1)

- Offspring of F1 fry mated with Red mated with Red will be ~75% red

- Offspring of F1 mated with another F1 will be ~25% red

Experiment:

- Separate one red male and one wild female into their own tank.

- Separate one red female and one wild male into their own tank.

- Observe offspring for coloration

- If no red coloration is displayed breed offspring (F1)

- Breed F1 male to Red Female

- Breed F1 female to red Male

- Breed F1 male to F1 Female

As the experiment continues I will give updates and include pictures.
