Answer:
Option B
Explanation:
Given ,
there is incomplete dominance of allele T and t when they pair together. Thus, TT genotype individuals are tall, Tt genotype individuals are medium heighted and tt genotype individuals are short.
Total number of plants [tex]= 100[/tex]
Number of short plants with genotype tt [tex]= 36[/tex]
If the given population is in HW equilibrium, then as per the 1st equilibrium rule of HW
[tex]p + q = 1[/tex]
where p is the frequency of dominant allele and q is the frequency of
recessive allele.
Here
[tex]q^2 = \frac{36}{100}\\= 0.36\\q = 0.6[/tex]
[tex]p + q = 1\\p + 0.6 = 1\\p = 1-0.6\\p = 0.4[/tex]
Frequency of tall individuals with genotype "TT"
[tex]p^2 = 0.4^2\\p^2 = 0.16[/tex]
Hence, option B is correct
