Biology

In a population of damselfish, the gene responsible for colorpattern produces three distinct phenotypes: solid blue (AA), blueand yellow striped (Aa), and solid yellow (aa). The (Aa) damselfishare more conspicuous and so are predated at a higher rate (SAa=0.6). suppose you counted 4400 solid blue,v2400 blue and yellowstriped, and 3200 solid yellow damselfish on a particular coralreef
(a) calculate the initial frequencies of the 3 genotypes and the2 alleles.
(b) what would the allele frequency for the recessive allele (a)be among the breeding adults after one generation (what isq₁)?
(c) if you counted 1000 baby damselfish from among the offspringof the adults in part (b), assuming they mate randomly, how many ofthem would be blue and yellow striped?
(d) if this form of selection continued for many generations,how would what your great-grandchildren observe in the futurecompare with what you might observe today?

a the HardyWeinberg principle applies to the individual gene with two alleles a dominant allele and a recessive allele a population with such a gene can be described in terms of its genotype numbersthe number of individuals with each of the resulting genotypesor in terms of genotype frequencies the frequency of each genotype is the number of individuals in the population with that genotype divided by the total number of See Answer
