A population of wild flowers was scored for flower color. There were 493 blue (BB) plants, 1633 violet (BR) plants, and 859 red (RR) plants. Remember to keep 4 decimal digits on all frequencies. • What is the frequency of the blue (B) allele? • What is the frequency of the red (R) allele? What is the expected number of blue (BB) plants? What is the expected number of violet (BR) plants?

A population of wild flowers was scored for flower color. There were 493 blue (BB) plants, 1633 violet (BR)
plants, and 859 red (RR) plants. Remember to keep 4 decimal digits on all frequencies.
• What is the frequency of the blue (B) allele?
• What is the frequency of the red (R) allele?
What is the expected number of blue (BB) plants?
• What is the expected number of violet (BR) plants?
• What is the expected number of red(RR) plants?
Keeping all decimal digits during your calculations and rounding your answer to 3 decimal digits, what is
the calculated chi-square value?
What is the number for the degrees of freedom?
What is the critical value? Round to two decimal places.
