When the mussels are predominantly in the Long Island Sound, they have less of a need to regulate the saltwater contents and, thus, the lap94 allele frequency is lower. The reason for some allele frequency of lap94 inside the Sound is because the muscle larvae can travel a long distance and carry the allele ]]> 2020-10-13 13:59:37 UTC https://padlet.com/mvblohm/c36brk5i2uzgg62p/wish/824900785 Marissa, Claire, Matt, Rylee https://padlet.com/mvblohm/c36brk5i2uzgg62p/wish/824902786 As salinity increases, the frequency of the lap94 gene increases. This is due to its ability to better maintain osmotic balance. Also individuals with the lap94 gene will migrate as larvae to areas of higher salinity because it is energy costing to have this gene in lower salinity levels.

It is high near the open ocean because of high salt concentration.The long distance dispersal of mussel larvae prevents the lap allele from disappearing completely in either environment. ]]> 2020-10-13 14:00:24 UTC https://padlet.com/mvblohm/c36brk5i2uzgg62p/wish/824904205 Jamie, Julia, Elinor, Jaia https://padlet.com/mvblohm/c36brk5i2uzgg62p/wish/824904424 Because the lap94 allele helps mussels maintain osmotic balance in salty water and because the mussels are able to produce generations dispersed over far distances, there is a range of lap94 alleles found across long Island, with more muscles displaying lap94 at the mouth of the sound and on the Atlantic side where there is the most salt.]]> 2020-10-13 14:00:28 UTC https://padlet.com/mvblohm/c36brk5i2uzgg62p/wish/824904424 Casey, Alexa, Kaitlyn, Claire https://padlet.com/mvblohm/c36brk5i2uzgg62p/wish/824904783  
As the saltiness of the water increases, the frequency of the lap94 allele correlates directly.

This being because lap94 helps maintain osmotic balance, and so f there is more salt present, the mussel needs more of those alleles to help continue balance. 

2) we said that this accounts for our data because the ability for the larvae to travel far distances allows the population to become more spread out. then we see the genetic differences (allelic frequencies) that arise due to the environment around them. ]]> 2020-10-13 14:01:00 UTC https://padlet.com/mvblohm/c36brk5i2uzgg62p/wish/824906630 Grace R, Brian S, Nada J, Bethany R https://padlet.com/mvblohm/c36brk5i2uzgg62p/wish/824907375 The allele frequency of lap94 increases as salinity increases so that they are able to maintain osmotic balance.
