Read the passage below and then answer the questions. Refer to the equations as needed. Ecologists think that they are seeing a change in an elk population that has moved 200 miles north over the last 20 years. They are now moving further into the snowy forests of Canada. It appears as though there are more albino elks than there were when the population was first studied. In order to determine if the population is actually changing, ecologists must first determine the allelic frequencies of the population. There are a total 126 elk in this population. 2. Within this population, 20 are albino. Albinism is caused by a recessive pigment, which indicates that 20 elk are homozygous recessive. What is the frequency of the homozygous recessive genotype? 3. Using your answer to \#2, solve for q: 4. Solve for p : 5. How many heterozygous individuals can be found in the population? 6. How many homozygous dominant elk can be found in the population? 7. The last known data of the elk population regarding albinism was recorded in 1995 . Then, the population had 92 individuals and of those 92,3 were albino. What was the allelic frequency of the recessive allele? 8. Has the allelic frequency changed since 1995? Offer an explanation as to why or why not:
