In an electrophoretic study of enzyme variation in a species of pelican, you find 77 a1a1, 45 a1a2, and 18 a2a2 individuals at a particular locus in a sample of 140. what are the allele frequencies for the a1 and a2 alleles? calculate the genotype frequencies for this locus.

Frequencies of allele and are and respectively.

Frequencies of Individuals with genotype respectively.

Explanation:

As per Hardy Weinberg's equation -

----------Equation (A)

-----------Equation (B)

Where "p" represents the frequency of "

"q" represents the frequency of "

represents frequency of individual  

represents frequency of individual

represents frequency of  individual

Here genotype frequencies are  -

Substituting this values in equation A, we get

Frequencies of allele and are -

For

Substituting this value in equation B, we get

Frequencies of allele and are and respectively.

Frequencies of Individuals with genotype  are respectively.

a time line cause it goes from 685 to 978

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
