Detailed explanation-1: -c B-allele frequency (BAF) is calculated by dividing the signal intensities of minor (B) allele by those of major (A) plus minor (B) alleles. In normal sample, three values of 1, 0.5, and 0 are obtained. A gain region generates four values (e.g., 0, 0.33, 0.67, and1) and it is interpreted as allelic imbalance.
Detailed explanation-2: -The total number of alleles = the total number of individuals x2. In the small population, there are 2 BB genotypes and 2 Bb genotypes, so 2x2 + 2 = 6 B alleles.
Detailed explanation-3: -Allele Frequencies In a sexually reproducing species, each member of the population has two copies of each gene. Therefore, the total number of copies of each gene in the gene pool is 200.
Detailed explanation-4: -Each gene is inherited in two alleles, i.e., one from each parent.
