5.    In a certain population of flowers, when red and white flowers are crossed they produce pink flowers.  A certain field has 1190 red flowers, 1070 pink flowers and 240 white flowers.  What is the frequency of individuals and alleles?

A. Total Number of flowers = 1190 + 1070 + 240 = 2500
    240 thin coat/2500 total = 0.096
    q2 = 0.096,  therefore the recessive allelic frequency is q = 0.31

B. p + q = 1
    p = 1 - 0.31
    p = 0.69 - dominant allelic frequency

C.
Genotype Designation  Frequency Percent
Homozygous Dominant pp or p2 (0.69)2 = 0.48 48%
Heterozygote pq  2(0.69)(0.31) = 0.43 43%
Homozygous Recessive qq (0.031)2 = 0.096 9.6%
The dominant allelic frequency is 0.69 and the recessive allelic frequency is 0.31.  The frequency of homozygous dominants is 0.48, heterozygotes is 0.43 and homozygous recessive is 0.096.
