In Hawaii, not only can we find the "typical" Monarch butterfly, orange in colour with black veins (see top figure), there is also a white morph. This rare white morph appears the same as the typical Monarch but it is white in colour (see bottom figure). The orange morph is the dominant phenotype for the wing-colour gene and the white morph is the recessive phenotype. In 1995, a study of Monarch butterflies on the island of Kauai indicated that this population was composed of 854 individuals. It was recorded that 166 of those individuals were the white morph. Given this information and the assumption that this population is in Hardy-Weinberg equilibrium, answer questions a & b*. a. What was the q? value in the 1995 population? b. What were the allele frequencies in the 1995 population c. A large decline in Monarch butterfly numbers in North America occurred in 2001 (debate as to the cause continues). A study in 2015 indicated that of the 270 butterflies on the island, 10% of the individuals showed the white morph colour. Assuming that this population is in HWE, determine p and q for the 2015 population. d. What proportion of the 2015 population had the heterozygous genotype? e. Did microevolution occur between 1995 and 2015? Explain your answer.

Transcribed Image Text:In Hawaii, not only can we find the "typical" Monarch butterfly,
orange in colour with black veins (see top figure), there is also a
white morph. This rare white morph appears the same as the typical
Monarch but it is white in colour (see bottom figure). The orange
morph is the dominant phenotype for the wing-colour gene and the
white morph is the recessive phenotype.
In 1995, a study of Monarch butterflies on the island of Kauai
indicated that this population was composed of 854 individuals. It
was recorded that 166 of those individuals were the white morph.
Given this information and the assumption that this population is in
Hardy-Weinberg equilibrium, answer questions a & b*.
a. What was the q? value in the 1995 population?
b. What were the allele frequencies in the 1995 population
c. A large decline in Monarch butterfly numbers in North America occurred in 2001
(debate as to the cause continues). A study in 2015 indicated that of the 270
butterflies on the island, 10% of the individuals showed the white morph colour.
Assuming that this population is in HWE, determine p and q for the 2015
population.
d. What proportion of the 2015 population had the heterozygous genotype?
e. Did microevolution occur between 1995 and 2015? Explain your answer.
