is this asking you to use the Hardy-Weinberg equation?

bringmetherain · Answer

Heres the whole question: In one species of shark, having a curved dorsal fin is dominant over a straight dorsal fin. This image represents a gene pool for a population of sharks off the coast of Hawaii. Calculate the allele frequencies, making sure to show your work. Furthermore, discuss whether this population has a high or low genetic variation for the dorsal fin trait. Finally, predict what would happen to the frequencies of D and d in the gene pool if having straight dorsal fins became advantageous

Considering it's talking about calculating the allele frequencies, I believe so. @rarecigs

Lemme give this a try. I just got the hang of the equation so ill give it my best

ya know rain im not really sure, im just getting nto gene pools myself

It's okay, I feel you xD

Um...

bringmetherain · Answer

Is the allele frequencies 64% for D and 35% for d

lol Sorry I can't help you on this!

bringmetherain · Answer

It's okay! Thanks for trying though!

qwertty123 · Answer

You welcome sorry I couldn't help. Um @dan815

Sorry i had lunch! but Right now its clear the ratio is 8:9 Have the phenotype for curved dorsal fins

bringmetherain · Answer

11 - Ds in gene pool
6 - ds in gene pool
17 - total alleles for fin trait in gene pool
Frequency of allele D - 11/18 = 61.11 %
Frequency of Allele d - 7/18 =  38.89%

@rarecigs is this correct?

anonymous · Answer

Sounds about right! Just make sure to have your work and explanation!

bringmetherain · Answer

* 7 ds

bringmetherain · Answer

and thanks!

anonymous · Answer

Not a problem =]

bringmetherain · Answer

But wait! would the population has a high or low genetic variation for the dorsal fin trait? High right? @rarecigs

anonymous · Answer

I only see 3 different gene variations in the picture you gave.. id imagine it being low?

bringmetherain · Answer

I just realize that! Thanks so much!
