While most commercial hens lay white eggs, certain Chinese and Chilean hens lay blue-green eggs. It is the result of an insertion mutation that causes blue eggshell pigment to be inherited as a dominant (B) allele (this was discovered by Punnett himself). In a flock of hens, there were 70 birds laying blue eggs and 30 laying white eggs. What is the Genotypic frequency for Bb?

every el niño cycle is different. every year.

. a balance and a graduated cylinder.

the hardy-weinberg equation is as follows:

where is homozygous dominant, 2pq is heterozygous, and is recessive.

we also know that:

so since we know that homozygous dominant is 0.53, we can solve for p:

so then we can solve for q:

so then we can solve for the heterozygous term:

so now we know that the percentage of the population that should be heterozygous is 39.6%.
