Storyboard Text
- Tomorrow is our out-of-town vacation, and we'll be gone for a week. What should I do with my cat? she's pregnant, I can't leave her for weeks.
- We'll take her to the veterinarian and keep her there until she gives birth, so she'll be safe.
- Please look after our cat; we'll be back home soon.
- Thank you, Doctor!
- You may rely on me to look after her  until she gives birth.
- After a week.....
- Don't worry, it's perfectly normal. That is an example of Multiple alleles, a non-Mendelian inheritance pattern in which there are more than the standard two alleles that code for a certain attribute in an animal.
- I'm wondering, why they aren't like their mother?
- In that case, That's what you're referring to when you say "incomplete dominance."
- Crossing between a black and white mouse producing a grey phenotype. This results in a third phenotype in which the expressed physical trait is a combination of the phenotypes of both alleles.
- Oh, wait, I recall something from genetics class.how about when you crossed the white and black mouse?
- In that case, that is "Codominance"   when the two parent phenotypes are expressed together in the offspring.
- Don't be confused haha.
- I'm still perplexed, but how did the children of a black mouse and a white mouse become black and white rather than grey?
- Oh, my boyfriend's here to pick us up. That was a fascinating conversation. I gained much knowledge.Thank you, Doc. Calico.
- You are welcome to visit my clinic again, and I hope you will not be confused by the topics we talked previously.
