On my homework there's a diagram of a flying bird with the allele of aa and then there's an arrow pointing to the land with 3 birds on the ground with the alleles AA. What would the allele frequency of A change from?
A)1 to .75
B)0 to .25
C)0 to .75
D)1 to .25
Unfortunately, Jiskha doesn't have a regular biology tutor.

Cant help but can give u advise go on BBC Bitesize. i AM new help me with science please!!!!!!!!!!! and wanna chat
To determine the allele frequency change, you would need to calculate the allele frequency before and after the scenario described in the diagram.
Before the birds on the ground arrived, there was a single flying bird with the allele aa. Since there is only one bird, the allele frequency of A would be zero. The frequency of a is 1.
After the birds on the ground arrived, there are now three birds with the alleles AA. Since there are three birds total, we divide the number of A alleles (3) by the total number of alleles (6) to calculate the allele frequency of A. The frequency of A would be 3/6 = 0.5.
Therefore, the allele frequency of A changed from 0 to 0.5. None of the answer choices exactly match this change.
