In a population of damselfish, the gene responsible for color pattern produces three distinct phenotypes: solid blue (AA), blue and yellow striped (Aa), and solid yellow (aa). The (Aa) damselfish are more conspicuous and so are predated at a higher rate (SAa =0.6). suppose you counted 4400 solid blue,v2400 blue and yellow striped, and 3200 solid yellow damselfish on a particular coral reef
(a) calculate the initial frequencies of the 3 genotypes and the 2 alleles.
(b) what would the allele frequency for the recessive allele (a) be among the breeding adults after one generation (what is q1)?
(c) if you counted 1000 baby damselfish from among the offspring of the adults in part (b), assuming they mate randomly, how many of them 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 future compare with what you might observe today?

Please write an essay for the following information for the Cell fusion technique:
Purpose - Brief description (one to two sentences) of the purpose of this method (ie. what is the general purpose for this technique? When would it be used?)
Background – This section will include a description of the concepts and theories that are needed to understand this technique.
Method description – this section will include an overview of the steps involved in carrying out the technique. This does not need to be as detailed as you would expect to find in a publication, but rather should include more of an outline of the experimental flow.
Advantages/limitations of the technique – This section should include at least 1 advantage and 1 limitation of the technique compared to other techniques.
