0.41 or 41%is the CW frequency.

Apply Hardy - Weinberg Equilibrium for two Genes.
( CW and CR); according to p^2 + q^2 + 2pq = 1

p^2 = 40, p = 0.447
q^2 = 22, q = 0.413 Frequency of allele 0.41

Total Population = 100
Red Flowers = 40
frequency = 40/100 = 0.4

Pink flowers = 38
frequency = 38/100 = 0.38

white flower = 22
frequency = 22/100 = 0.22

Let: C^rC^r Red flower = p^2
C^rC^w Pink flower = 2pq
C^wC^w White flower = q^2

Use Hardy Weinberg principle p^2 + q^2 = 2pq = 1

Frequency of CW allele = 1/2(2pq) + q^2

Divide the 2pq by 2 because, needed to account only for C^w and not the partner C^r.

So, 1/2(0.38) + 0.22 = 0.41 or 41% answer.

Hope this helps

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

0.41

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
