With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.) 

You do each PCR reaction and load each one into a separate well of an agarose gel, and then run the gel.

 

 

Why is it that some people show only one band?

if the forward ( p in to q) and reverse ( q in to p) mutation rates for alleles at a locus are 1×10−1 and 1×10−2 per generation, respectively and the allelic frequencies are p = 0.20 and q = 0.80. if you assuming random matting population. Which of the following observation correct?

 In a human population, the gene frequencies of the alleles for the ABO system are as follows:

A = 29%                         B = 7%                                    0=64%

Assuming complete random mating and Hardy-Weinberg equilibrium,

What are the blood type A frequencies in this population?

Which statement is not an assumption of the Hardy–Weinberg law?

a. The allelic frequencies (p and q) are equal.

b. The population is randomly mating.

c. The population is large.

d. Locus is di-allelic

Migration causes changes in the allelic frequency of a population by introducing alleles from other populations. The magnitude of change due to migration depends on
