Chapter 13 Incomplete Dominance and Codominance

Since you have about a 3:1 ratio on both of the first two, the first two are "The mutant allele is dominant to its corresponding wild-type allele."

Since you have a 2:1:1 ratio, this implies incomplete dominance ("doses" of an allele influence the phenotype), therefore heterozygotes (Gg) are green, homozygotic wild type (gg) are dark green, and homozygotic pale (GG) are pale.  "The mutant allele is neither dominant nor completely recessive to its corresponding wild-type allele."

The  third question: since you have twist, forked, and twist/forked, it's like a blood type (A, B, AB), so "The forked mutation and twist mutation are codominant alleles of the same locus"

When you find out the answer, please come and update us.  If it was correct, mark as solved.  Thank you.

TWIST -"The mutant allele is dominant to its corresponding wild-type allele."

FORKED - "The mutant allele is dominant to its corresponding wild-type allele."

PALE - "The mutant allele is neither dominant nor completely recessive to its corresponding wild-type allele."

The correct answer is:

Twist: The mutant allele is dominant to its corresponding wild-type allele

Forked: The mutant allele is dominant to its corresponding wild-type allele

Pale: The mutant allele is neither dominant or completely recessive to its corresponding wild-type allele

Janebercilla is correct. I just completed this assignment.

That's what I put.

Now that I go back and look at it, yup, you did. Sorry I can't update my post now. It was late, and I just skimmed over the responses. The answer to the third question is what threw me off. I didn't realize it was a response to a different question at the time. I confused it with an answer to the other questions. Late hours and homework don't mix lol. Sorry once again, but gave you best answer vote and rep point if it helps.  

hah no sweat of course

thanks

thanks!

THANK YOU!!

Thank you for your contribution.

Will someone for the love of god and all that is holy help me understand these genetic analyses

thank you

thanks
