Honors Bio class 16

Today in class we discussed how to solve for allele frequency based on population and genes. we used the equation p^2 + 2(pq) + q^2 = 1, and p + q = 1. p^2 = AA, q^2 = aa, 2pq = Aa.
We also mentioned the Hardy-Weinberg ideals for a population so that nothing influences the result:
We applied this in the activity we did using sex gamies: 
After we collected our data we put them I to columns and analyzed it. We found that the majority would always be the dominant trait, and therefore the recessive gene would on be present in those with heterozygous genes. For the recessive gene to appear, we would have to mate with a Heterozygous + Heterozygous, or introduce hh back into the gene pool. However, through natural selection, the recessive gene hinders those who carry it (sometimes), and can cause them to have a shorter life expectancy,
We then took a really hard quiz on what we had learned (calculating frequencies).
