In fruit flies, the allele for ebony body color is a nonlethal, recessive mutation. the table below shows the number of ebony and brown fruit flies, over several generations, in a population for which only the ebony and brown alleles are present. generation brown body ebony body 1 490 4 2 857 7 3 612 5 4 367 3 6 980 8 is evolution occurring in this population? explain your answer using the hardy-weinberg equation. ! i need someone who can me understand how to apply the hardy-weinberg equation !

In the first generation, there are 490 brown fruit flies and 4 ebony fruit flies. This mean that the frequency of the brown (p2) is 490/490+4 = 0.992 and the frequency of the ebony (q2) is 4/490+4 = 0.008. The frequency of the dominant allele is p=√0.992=0.995 and the frequency of the recessive allele is q=√0.008=0.089. p+q=1 (HW)

The Hardy-Weinberg equilibrium principle describes that frequency of alleles is unchanged through the generations.

Gen 2.  

p2= 857/857+7=0.991

q2=7/857+7=0.008

Gen 3.

p2= 612/612+5=0.991

q2=5/612+5=0.008

Gen 4.

p2= 367/367+3=0.991

q2=3/367+3=0.008

Gen 5.

p2= 980/980+8=0.991

q2=8/980+8=0.008

The frequency of alleles is unchanged, population is not evolving.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
