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.
n each case where Mendel crossed (i.e., mated) two different true-breeding plants as parents, the offspring displayed only one of the two traits seen in the parents. For instance, a cross between a true-breeding “tall” plant and a true-breeding “short” plant produced offspring that were all “tall.” This observation supports which principle of genetics? a. The law of segregation b. The law of independent assortment c. Dominance and recessiveness d. Allele anomaly e. Gene linkage

1. Incomplete dominance governs the pigment gene of a flower. A mating between heterozygotes yields the following phenotypic ratio: 10 yellow flowers, 35 pink flowers and white flowers. Which statement describes the situation? a. The flower pigment gene is defined by a pink and yellow allele. b. The heterozygotes were yellow. c. The heterozygotes were white. d. The flower pigment gene is defined by a red and a white allele. 2. Mendel's rules do not correctly predict patterns of inheritance for tightly linked genes or the inheritance of alleles that show incomplete dominance. Does this mean that his hypotheses are incorrect? A. Yes, because they are relevant to only a small number of organisms and traits. b. Yes, because not all data support his hypotheses. c. No, because he was not aware of meiosis or the chromosome theory of inheritance. d. No, it just means that his hypotheses are limited to certain conditions. 3. Discuss the inheritance of hemophilia

4. The inheritance of coat colour in cattle controlled by multiple alleles with a dominance hierarchy as follows: S > sh > sc > s. The S allele produces a white band all over the cattle’s body known as ‘Dutch band’, the sh allele produces spots on the skin known as ‘Hereford’, the sc allele produces solid colour, and the s allele produces ‘Holstein’ spots. Homozygous ‘Dutch band’ males are cross to ‘Holstein’ females. The F1 females are crossed to ‘Hereford’ males of the shsc genotype. With the aid of genetic diagram, determine the expected genotypic and phenotypic frequencies in the F2 progeny.
1. Construct a pedigree chart of the trait traced in the situation below.2. The pedigree chart must be constructed with the names and genotypes at the bottom of every individual in the chart.If it is autosomal: Always use the first letter of the dominant trait to represent the dominant allele. For example, if the dominant trait is red, so the allele R-red, while r-yellow. For example, if the person is homozygous dominant for curly hair, we write CC as his genotype. If sex-linked, do not forget to write the parents’ chromosomes (XX-female, XY-male), with their corresponding superscripts (dominant or recessive). The superscript must be based on the first letter of the disorder. For example, the mother is a carrier of hemophilia (which is x-linked recessive), so we write XHXh. If the father has hemophilia, we write XhY. Put the pedigree chart using code properly. The situation is given below: Trait: NeurofibromatosisThe dominant form is neurofibromatosis, caused by the production of…

Color blindness is typically an inherited genetic condition in which individuals have a decreased ability to see color or differences in color. Color blindness only occurs in individuals who have two recessive alleles for the condition. Normal color vision is due to a dominant allele (C) Color blindness is due to the recessive allele (c) a) If Susan is homozygous for normal vision, and Matt is homozygous for color blindness, what is the likelihood (in percentage) that their son Alex will have color blindness? Perform a Punnett Square (either below or by hand on paper) to find the probability. Provide your answer in a full sentence. If you did the Punnett Square by hand, attach your photo to the next question.
