In a hypothetical species of butterfly, wing spots arecontrolled by a single locus where BB individuals have blue spots,YY individuals have yellow spots, and BY individuals have greenspots. Ten years ago, a previous collector randomly collected 1000butterflies and reported finding 90 blues, 420 greens, and 490yellows. You collect 40 blues, 320 greens, and 640 yellows. Hasthere been evolution in this population? If yes, is naturalselection involved? Explain and justify your answers.
This is my third time posting this question, please don't answerit if youre going to give me p2+q2+2pq=1
I'm not asking if evolution is happening 10 years ago and if itis happening now, I'm asking has evolution happened comparing 10years ago to now!
So can you please calculate the expected genotypic or phenotypicfrequencies (of each of 10 years ago and now) using HWE mathp2+2pq+q2p2+2pq+q2. Then calculate the chi-square values, which areadjusted measures of deviation based on each individual frequency.Fail the test, and you know you have a violation of HWE. It ispossible to test for signatures of selection (please test forselection as well) .
I hope you dont just give me a 2 line answer or give me a pastedanswer of the old questions! Im definitely going to give a thumbsdown as this is the third time I ask this.
