Worked Solution & Example Answer:In a species of marine snail the colour of the shell is controlled by a single gene with 2 alleles, G and g - VCE - SSCE Biology - Question 24 - 2003 - Paper 1

Step 1

The frequency of the g allele in population 5 is

96%

114 rated

Answer

To find the frequency of the g allele in population 5, we can use the formula:

f(g)=1f(G)f(g) = 1 - f(G)

From the table, the frequency of the G allele in population 5 is 0.7. Therefore,

f(g)=10.7=0.3f(g) = 1 - 0.7 = 0.3

However, the values provided are: A. 0.15 B. 0.35 C. 0.35 D. 0.7

The closest answer to 0.3 in the options is 0.35 (option B).
