In a population of 100 four-o'clock flowers there are 40 red-flowered plants (crcr), 38 pink-flowered plants (crcw), and 22 white-flowered plants (cwcw) what is the frequency of the cw allele in this population

0.41

Explanation:

In a population of 100 four-o'clock flowers there are 40 red-flowered plants (crcr), 38 pink-flowered plants (crcw), and 22 white-flowered plants (cwcw) what is the frequency of the cw allele in this population

four-o'clock flower has two alleles for each gene. making 2*100=200

The white flowered plants have two copies of CW alleles, making 2*22=44

The pink flowered plants have one each, making 1*38

To get the probability or the frequency of occurrence, we simply find

the frequency of the cw allele in this population=

Total number of white flowered plants x two+Total numbered of pink flowered plants*1/(The total population*2)

22*2+38*1/(100*2)

82/200
