oratory Investigation #1 Hardy-Weinberg: Is the ECU populatio it flies in Hardy-Weinberg equilibrium? You discover a new population of cotton rats on Bermuda Island immigrated from the mainland on ships from different ports. You c following genetic data for the enzyme lactate dehydrogenase table below. Use these data to answer the following questions. 8. (Ldh), shown in the lo hat are the population's What are the allelic frequencies for the ney nopulation? What are the popu genotypic frequencies? Is this population in H-W equilibrium? Offer an explanation Rat # Sex |Ldh genotype LiL2 LILI LiL LiLz L:L: LiL L2Lz L:Lz LiL2 LiL DOES NUr MEAN HwE. 10

Explanation / Answer

No, the population is not in HW Equilibrium. The equilibrium thrives on certain assumptions which include that there is no migration and the population is considerably large. The data is presented for only 10 individuals for a population which faces immigration of new members with the arrival of each ship. These disturb the equilibrium and hence the ratio.

Genotype Genotypic Frequency= Allelic frequency= L1L1 0.4 p2 p=0.639 L1L2 0.2 2pq L2L2 0.4 q2 q=0.639
