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
Answer
To find the frequency of the g allele in population 5, we can use the formula:
From the table, the frequency of the G allele in population 5 is 0.7. Therefore,
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).
