Title: MasteringBIO: Calculating allele frequencies in a gene pool
Post by: tatda on May 2, 2013
In the beetles described in the animation, there were two alleles for color, brown and green. Suppose that you discover a very small population of these beetles, consisting of the individuals shown below. How can you calculate the frequency of each allele in this population?

(http://session.masteringbiology.com/problemAsset/1135065/15/MB_1135065_001_revised.jpg)

1. To calculate the frequency of the brown allele, count the number of total number of alleles in this population.

2. ln this beetle population, the number of brown alleles is?

3. ln this beetle population, the total number of alleles for color is?

4. The frequency of brown alleles in this beetle population is?

5. The frequency of green alleles in this population is?

Terms:
Brown Alleles
Green Alleles
0.4
0.6
2
8
10
20

Double green chromosome suggests it is homozygous dominant: 4 out of 10
Single green chromosome suggests it is heterozygous: 4 out of 10.
Double brown suggests it is homozygous recessive: 2 out of 10.

Use the Hardy-Weinberg equation: P2 + 2PQ + Q2 = 1

Let me know if you still need help ;)

Can you tell me how did you get 8 for number 2 please. Thanks

You simply count each brown allele, you do not count the phenotypes.
