In an isolated population, the frequencies of the IA, IB, and i alleles of the A–B–O blood type gene are, respectively, 0.15, 0.25, and 0.60. If the genotypes of the A–B–O blood type gene are in Hardy–Weinberg proportions, what fraction of the people who have type A blood in this population is expected to be homozygous for the IA allele?

A population of humans contains the following frequencies for the A, B and O alleles at the I blood type locus: A = 0.6, B = 0.2 and O = 0.2. A female of blood type A marries a type B male. What is the probability that they produce an offspring of blood-type AB?

IA and IB are codominant alleles at the ABO locus, whereas IO is recessive. Individuals with hh genotypes at another locus called FUT1 (which involves the Bombay phenotype) do not express antigens encoded by the ABO locus at all. This examplifies A. pleitotropy B. dominant epistasis C. recessive epsistasis D. incomplete dominance E. epigentics

4a) The frequencies of alleles A and B in a pool of gametes are A= B= 0.5. The gametes randomly unite to form 200 zygotes. What are the numbers of each genotype among the zygotes? (5 pts) b) As these zygotes develop into adults, 92% of individuals with genotype AA, and 80% of individuals with genotype BB were captured and killed by a predator because they were too slow. Does the surviving population of adults appear to be in HW...

You will use A, B, and O for these questions to represent the alleles in this example. The ABO blood system works in a Mendelian fashion, but has 3 possible alleles at one locus (A, B, and O alleles). Each person can have only 2 of those alleles in their genotype. A and B are both dominant (and so can be co-dominant), and O is recessive to both A and B. So, for example, if you have B blood type,...

A small portion of a population migrates to an isolated island. Its genotypic frequencies are 0.8 AA, 0.1 Aa and 0.1 aa. These individuals start a new population on this island. What phenomenon is being described here? Calculate the allele frequencies for this new island population. Assume that this population is not undergoing evolution and undergoes random mating. What genotypic frequencies will you see in this population after one generation of random mating? What will the allele and genotype frequencies...

In a population where skin color gene can be determined by 4 alleles B(black)=0.412561 o(olive) = 0.312450 y(yellow) = 0.112689 w(white) =0.123540. The gene for skin type can be determined by 3 alleles N(normal)=0.425789 d(dry)= 0.345689 x(oily)=0.214130. The gene for skin elasticity can be determined by 2 alleles E(elastic)= 0.456820 and e(non-elastic)= 500123. Assume Hardy-Weinberg equlibrium, what is the frequency of getting yellow, normal, elastic skin? (p2 + 2pq + q2 + 2pr + 2qr + r2 = 1). ?

1) Suppose that a certain population of 100 individuals possesses two alleles (A and B) at a certain locus, and initially consists of the following numbers of genotypes: AA = 9, AB = 42, BB= 49. a) Calculate the initial frequencies of alleles A and B. b) Now suppose that 16 individuals with genotype BB do not survive to reproduce. Calculate the new allele frequencies among the remaining individuals that do reproduce. Assuming that these remaining individuals mate randomly, calculate...

In an African population the ABO blood group antigens alleles at the I locus were found in the following frequencies: IA = 0.12 IB = 0.56 IO = 0.32 What are the expected genotype frequencies in the population? what are the expected frequencies of the A, B, AB, and O blood types? (remember IA points) and IB are codominant alleles and IO is a null allele).
