- Codominance ABO blood typing is an example of codominance, where A and B are both dominant to O. A woman who is AB type has a child with a man who is O type. Use I allele formatting to designate each genotypes: IA IA, IA i, IB IB, IB i, IA IB, ii A) List the genotype of each parent. B) Complete a Punnett square. List all the genotypes for the predicted offspring of this mating (using the format of genotypes listed above) C) What is the probability that any of their offspring will be O type? D) What is the probability that any of their offspring will be AB type?arrow_forwardConsider the MN blood system in humans. This blood system consists of only two alleles, M and N, and they are codominant to each other. Three genotypes are possible, and these genotypes can be easily identified through simple blood typing procedures, including the heterozygous MN due to the codominant mode of inheritance. Consider the following data: Phenotype Genotype Number of individuals M MM 89 MN MN 162 N NN 79 1. How many alleles exist in this population? 2. What is the genotypic frequency of the M blood type in the population? 3. What is the allelic frequency of M? 4. What is the allelic frequency of N? 5. What is the genotypic frequency of MN?

She calls this mutation quiver, qu, and determines that it is due to an autosomal recessive gene. She wants to determine whether the gene encoding quiver is linked to the recessive gene for vestigial wings, vg. She crosses a fly homozygous for quiver and vestigial traits with a fly homozygous for the wild-type traits, and then uses the resulting F, females in a testcross. She obtains the flies from this testcross. Phenotype Number of flies vg* qu+ 230 vg qu 224 vg qut vg* qu 97 99 Test the hypothesis that the genes quiver and vestigial assort independently by calculating the chi-squared, X², for this hypothesis. Provide the X2 to one decimal place. X2 = Does the X value support the hypothesis that the quiver and vestigial genes assort independently?

Although Laurlanthalasa, Princess of the Qualinesti elves, is known for riding into battle on a silver dragon, this is not her main form of transportation. She generally travels by way of griffon. Although the allele for a "crown" of feathers around the head is dominant, it is rarely found in the wild. This may be due to the fact that it makes the griffons stand out, thus making them less effective hunters and more visible to their natural enemies, evil chromatic dragons. This scarcity also makes them prized by elven royalty. Lauralanthalasa was given a breeding pair of bald griffons by an admirer who claims that they are both hybrids for the crowned gene. Create a Punnett Square to determine if Lauralanthalasa will have any chance using these two griffins to produce crowned offspring.

Use the unrounded and complete values when computing for the genetic gain; 2. Upon encoding, all final answers should be rounded-off to TWO decimal places. Examples: 3.5798 = 3.58, 0.0079 = 0.01, 0.00000008 = 0.00; 2. Report your answers as NUMERIC VALUES only. Please exclude the units; 3. Write ONLY one answer for each question. Avoid using "or", "/", "&" and "and". Provide only what is asked to you; 4. AVOID using unnecessary PUNCTUATIONS (. , ? 1; ; etc.), SYMBOLS ( []{ } etc.) and SPACES (before or after your answer). Please follow these instructions carefully. Prediction of Genetic Gain. If the milk yield of a herd of cow is 6,479 kg while those kept for breeding is 6,890 kg, and the h2 estimate of milk yield is 0.85. And the generation interval of dairy cattle is 4 years. What will be the expected genetic gain in the milk yield (kg/year) of the next generation?arrow_forward1 (b). Nowadays, newborn babies are required to be tested for phynylketonuria (PKU), an autosomal recessive genetic disorder. If untreated, individual homozygous for PKU suffer mental retardation. In a recent year, 4 PKU babies were detected out of 126,o00 tested. Assuming Hardy-Weinberg conditions, What is the percentage of heterozygous carriers?
