Question
Lab 8 Part 2: Spirit Bears In Lab 6 you learned about spirit bears, white bears that are actually a colour variant of the black bear (Ursus americanus), which are typically either black or brown. Kermit Ricland and his colleagues collected biological samples from bears on three islands in the Pacific Northwest and determined their genotypes at the mer/ locus, which is where the mutation that confers white coat colour in bears is located. They found 42 hemozygous dominant bears (B8), 24 heterosygous bears (Bb), and 21 homozygous recessive bears (bb). 6. Using the work you've done already in this lab as a model, determine whether the black bear population is in Hardy-Weinberg equilbrium with respect to the mar i locus. Show your reasoning and calculations clearly. Use the table below and the next page (blank) if you need it Table 2. Genotype (class) Observed # | Expected # (o-e) (o-e) 21 1/2-Slo6|8.ugau |2.0699| s.7607 Total P Ko.ooSExplanation / Answer
Finding the p and q values from the values of homozygous individuals.
p2 = 42/87 =0.48, p =0.6
q2= 21/87= 0.24, q = 0.4
Since the total is 1.00, the population is in Hardy Weinberg equilibrium.
The title for the experiment would be Spirit bears are in equilibrium. The reasoning is given above
