• Explaining prevalent mutations in a small and large population

  That is, to be classed as a polymorphism, the least common allele must have a frequency of 1per cent or more in the population. If the frequency is lower that this, the allele is regarded as a mutation.

• What is the probability that their next child will be a female who has normal vision and is type O?

  Let's use the "c" designation for the recessive colorblind allele and "C" for the normal allele.

• Offspring's Blood Type

  The father could be homozygous with two alleles of type A or he may be heterozygous with one allele of type A and one allele of type O.

• What can cause a change in allele frequency

  This is a change in allele frequency and occurs as populations evolve. The question asks you to examine each answer and decide if it will cause a change in allele frequency.

• Population-Genetics Problems using Hardy-Weinberg Equilibrium.

  Remember the symbol p represents the frequency of one allele and q represents the frequency of the other and that a pair of alleles determines that flower color.

• To calculate geotype frequency

  Calculate the frequency of the black allele (B) and the spotted allele (b) in the population, as well as the frequency of each genotype (BB, Bb, and bb) in the population.

• Population Genetics

  q = f(r) = the frequency of the r allele = (16 + 7 + 7)/200 = 0.15 p = f(R) = the frequency of the R allele (77 + 77 + 16)/200 = 0.85 Notice that p + q = 1.

• Sex Determination and Sex Differentiation in Humans

  An example is the ABO blood group that are determined by three alleles of one gene that show different types of interaction to produce 4 blood types of ABO system. The allelic systems include 3 major alleles i, IA, and IB .
