If you examine a population for a particular gene where b represents the dominant allele and b represents the recessive allele, you find that the allele frequencies for this gene are p = 0.3 and q = 0.7. if this population is not evolving, what would be the frequency of the heterozygous genotype? a. 0.09 b. 0.21 c. 0.30 d. 0.42 e. 0.49

Assuming Hardy-Weinberg equilibrium

B=dominant, P(B)=0.3
b=recessive, P(b)=0.7

Genotypes are given by:

(P(B)+P(b))^2=(0.3+0.7)^2=0.3^2+2*0.3*0.7+0.7^2=0.09+0.42+0.49=1

                                                                                         P(BB)+P(Bb)+P(bb)=1

Which means

P(BB)=0.09   (homozygous dominant genotype)

P(Bb)=0.42   (heterozygous genotype)

P(bb)=0.49   (homozygous recessive genotype)

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
