Peregrine falcons are one of the several species of raptorswhose populationsdeclined       dramatically inthe mid-60's after exposure to pesticides that caused them to layvery thin-shelled eggs.  In fact, the population ineastern North America disappeared entirely, but birds have beenreintroduced.  Even though use of DDT has been banned inthe USA, it is still used elsewhere, and is manufactured in theUSA, and so species such as peregrines are still exposed to someextent to these toxins.  At a locus coding for an enzymeinvolved in laying down calcium in the eggshell, birds of genotypeAA lay perfect eggs, while those that are Aa suffer 10% eggbreakage (sAa = 0.10), and those that are aa suffer 70%egg breakage (saa = 0.70).  The originalpopulations starts with 450 individuals of genotype AA, 380 ofgenotype Aa, and 170 individuals of aa. Â
(a)  What is the startingallele frequency for the (A) allele (in other words, what isp0)?   What would the allele frequencyfor the (A) allele be in the adults after one generation (what isp1)?
(b)Â Â Â If thep1 generation of adults reproduced by random mating, howmany chicks in the population would you expect to find with the aagenotype (the most fragile) if you counted a total of 100 babyfalcons?
