I am practicing discerning heriditary blood type questions. Please guide me with my first question. Chapter 22 review (No points, these are simply for practice)In humans, the ABO blood groups are controlled by three alleles (only two ofwhich occur in any one individual): the alleles for A and B type blood are co-dominant toward each other, and both are dominant to the allele for O typeblood.A.lf a person with type AB blood has children with someone with type Oblood, what are the possible phenotypes (blood types) of their offspring?B. Determine the genotypes of the parents, if one parent has type A bloodand the other has type B, but all four blood groups are represented in thechildren. Express using the appropriate symbols.C. Determine the genotypes of the parents, if one parent has type AB andthe other has type B, but 4 of the children have type A blood, 1/4 have typeAB, and 1/2 have type B.

A farmer raises black and white chickens. To his surprise, when the first generation of eggs hatch all the chickens are black with white speckles throughout their feathers. What should the farmer expect when the eggs laid after interbreeding the speckled chickens hatch? All the offspring will be speckled 75% of the offspring will be speckled, and 25% will be black 50% of the offspring will be speckled, 25% will be black, and 25% will be white 50% of the offspring will be black and 50% of the offspring will be white.
Labrador retriever's fur color is controlled by two alleles, E and B. Any dog with the ee genotype develops into a yellow lab, while B_E_ dogs become black labs and bbE_ dogs become chocolate labs. This is an example of.____ epistasis codominance incomplete dominance linkage
A single allele gives rise to the Hbs form of hemoglobin. Individuals who are homozygous for the allele (HbS/HbS) develop sickle-cell anemia (Section 9.6). Heterozygous individuals (HbA/HbS) have few symptoms. A couple who are both heterozygous for the HbS allele plan to have children. For each of the pregnancies, state the probability that they will have a child who is: a. homozygous for the HbS allele b. homozygous for the normal allele (HbA) c. heterozygous: HbA/HbS
25., Snow geese (Chen caerulescens) come in two color types, white “snows” and “blues” with dark bodies. A single gene controls coloration, where the dark (“blue”) allele (D) is dominant. A population of 30,012 geese includes 9236 dark individuals. Genetic testing reveals that 7636 of the 9236 dark individuals are heterozygous (Dd). How many individuals are dd? 7636 13140 1600 20776
The A and B antigens in humans may be found in water-soluble form in secretions,including saliva, of some individuals (Se/Se and Se/se) but not in others (se/se). The populationthus contains “secretors” and “nonsecretors.”(a) Determine the proportion of various phenotypes (blood type and ability to secrete) in matingsbetween individuals that are blood type AB and type O, both of whom are Se/se.(b) How will the results of such matings change if both parents are heterozygous for the genecontrolling the synthesis of the H substance (Hh)?
3. Codominance is when two dominant alleles of contrastingpair fully expressed at the same time in heterozygousindividual. Which of the following situation is an example ofcodominance?A. Jo mated the red bull with the white cow to produce a roan cow.B. Melissa traces her blood type by crossing the blood type of herparents.C. James passed a genetic disorder hypertrichosis pinnae aurisor hairy ear to his son.D. Tess crosses the red carnation flower plant with white flowercarnation plant to produce a pink flower plant.
Color blindness in humans is an X-linked recessive trait. Approximately10% of the men in a particular population are color blind.a. If mating is random with respect to the color-blindness locus, what isthe frequency of the color-blindness allele in this population?b. What proportion of the women in this population are expected to becolor blind?c. What proportion of the women in this population are expected to beheterozygous carriers of the color-blindness allele?
Part 1 - With use of Punnett diagrams discuss how the results of experiments carried out by Austrian monk Gregor Mendel on pea plants brought about the Law of Dominance, the Law of Segregation, and the Law of Independent assortment. Part 2 - In humans, the gene that produces the disease Sickle Cell Anaemia is recessive to the gene for healthy haemoglobin production. a) How can two phenotypically healthy parents have a child who suffers from Sickle cell Anaemia? In your answer use suitable letters to show the genotypes of the parents and construct a Punnett diagram to show all the possibilities of the children's genotypes. b) Based on the outcome of your Punnett diagram, state and explain the probability of a child being a sufferer of Sickle Cell Anaemia and the probability of a child not suffering from the disease. c) If an individual who suffers from Sickle cell disease has a child with someone who is healthy (and not carrying the sickle cell gene), what is the probability that…
#20 Scenario 1 (do not use any reasoning) Please answer questions 1-4 in part 1 and part 2 A population of beetles in the species Dwayne therock (I made this up) are living in a rotting log in a forest. In these beetles, color is controlled by 1 gene. There are two alleles - R for Red and r for orange. this is an autosomal trait with complete dominance Questions part 1 What are all the possible genotypes a red beetle could have? (list them all) What phenotype would a heterozygous beetle have? If two heterozygous beetles had offspring, what are the chances (in %) of having an orange beetle offspring? If a homozygous dominant beetle and a homozygous recessive beetle had offspring, what are all the possible genotypes of their offspring?

There are two alleles - R for Red and r for orange.…
Scenario A In goats, black fur is dominant to red fur. The gene for this trait can be described as Bb (if you forgot why this is so, go back and reread the background information at the beginning of this exercise). A homozygous black female goat (nanny) is crossed with a heterozygous male (billy). 1 What is the genotype of the nanny? What is the phenotype of the nanny?
26. Snow geese (Chen caerulescens) come in two color types, white “snows” and “blues” with dark bodies. A single gene controls coloration, where the dark (“blue”) allele (D) is dominant. A population of 30,012 geese includes 9236 dark individuals. Genetic testing reveals that 7636 of the 9236 dark individuals are heterozygous (Dd). What is the actual frequency of allele D? 0.819 0.181 0.435 0.347
ACTIVITY 3: Incomplete dominance vs. codominance Coat color in dragons is controlled by 2 alleles. A black dragon is crossed with a white dragon and all of the offspring are gray.
