The dominance pattern of a gene can be determined from the phenotypes of the parents and offspring. In the examples below, assume that each parent is homozygous for the specific allele and that the progeny are heterozygous. Classify each example as either complete dominance, incomplete dominance, or codominance. Complete dominance Incomplete dominance Codominance Answer Bank A black sheep and a white sheep produce a gray lamb. A white cow and a red bull have a calf that is white with red spots (roan colored). A mother with type A blood and a father with type B blood have a daughter with type AB blood. A pea plant with all purple flowers and a pea plant with all white flowers produce a pea plant with all purple flowers. A moth with red wings and a moth with yellow wings produce a moth with orange wings.
Which of the following statements is/are false regarding alleles? (Select all correct answers.) For a given species, every gene has only two alleles All disease causing alleles are recessive to the wild-type allele A single allele can be recessive to the wild-type allele for one phenotype, but dominant to the wild-type allele for a different phenotype. For any pair of alleles of a given gene, the same dominant/recessive relationship will be found for all phenotypes affected by that gene
Coat color in labradors is determined by alleles of two unlinked genes, B and E. The coat colors of dogs with various genotypes are as follows: BB EE black Bb Ee black bb Ee brown (chocolate) Bb ee yellow bb ee yellow Which of the following cannot be inferred from this information? e and b alleles complement one another O e is dominant to b Oe is epistatic to b B is dominant to b
Which of the following is an example of incomplete dominance? Select ALL that apply. RR and Rr seeds are round, whereas rr seeds are wrinkled, Rr seeds contain 50% as much starch as RR seeds. o AcR individuals produce red flowers, CWCW individuals produce white flowers, and heterozygotes (C*C") produce pink flowers. AP individuals produce both the A and the B antigens. individuals produce the A antigen.
Gregor Mendel discovered the basis of heredity with his sweet pea plant experiments. In his studies, he determined that certain traits, such as pod color and pea shape, express complete dominance. Trait Dominant Recessive Pod color Yellow Green Pea shape Round Wrinkled A cross occurs between a plant with heterozygous yellow pods and wrinkled peas and a plant with green pods and heterozygous round peas. What is the probability that the offspring will exhibit recessive genes for both traits? a) 1/2 b) 1/4 c) 1/8 d) 1/16
In domestic cats, the allele (L) is a dominant allele for short-hair trait. The recessive allele for long hair is (I). A female cat with a LI genotype has kittens with a male cat with a II genotype. What is the probability that a kitten has short hair? Hint: it may be helpful to draw a Punnett Square.
For some traits, one allele is not completely dominant to another. Incomplete dominance occurs when neither allele dominates over the other. The resulting phenotype of heterozygotes is an intermediate of the two extremes. Incomplete dominant genes control snapdragon flower color. Red flower plants crossed with white flower plants produce offspring with pink flowers. One human trait that is thought to be inherited in this fashion is hair structure. Curly hair and straight hair are due to homozygous genotypes and wavy hair is produced by the heterozygous genotype. An incompletely dominant gene also controls the plumage of chickens. Black plumage and white plumage are due to homozygous genotypes and a blue-grey color results from a heterozygous genotype. Using Punnett squares and variations of the letter “B”, answer questions 1-3 and use variations of the letter “R” to answer questions 4-5. What type of offspring and in what ratio would you expect from a cross between a black…
Consider two blood polymorphisms that humans have in addition to the ABO system. Two alleles LM and LN determine the M, N, and MN blood groups. The dominant allele R of a different gene causes a person to have the Rh+ (rhesus positive) phenotype, whereas the homozygote for r is Rh− (rhesus negative). Two men took a paternity dispute to court, each claiming three children to be his own. The blood groups of the men, the children, and their mother were as follows:From this evidence, can the paternity of the children be established?
In shorthorn cattle, coat color may be red, white, or roan. Roan is an intermediate phenotype expressed as a mixture of red and white hairs. The following data were obtained from various crosses: red * red ¡ all red white * white ¡ all white red * white ¡ all roan roan * roan ¡ 1/4 red:1/2 roan: 1/4 white How is coat color inherited? What are the genotypes of parents and offspring for each cross?
In humans, "unattached" earlobes are dominant over "attached" earlobes. "Widows peak" hairline is dominant over "non-widows peak" hairline. Use E and e for the earlobe phenotype alleles, and W and w for the hairline phenotype alleles. A female and a male, both with genotype EeWw have a child. What is the probability it will be a boy, and have attached earlobes and a widows peak hairline?
Suppose a geneticist is using a three-point test cross to map three linked rabbit morphology and behavioral mutations called si, sf, and H. The gene si is associated with the silky fur phenotype, and sf is associated with the short-footed phenotype. Both si and sf are recessive mutations with respect to wild type. H is a dominant mutation that confers the hyper phenotype. The geneticist first crosses true-breeding hyper rabbits to true-breeding silky fur, short-footed rabbits. Next, the geneticist backcrosses the F₁ progeny to the silky fur, short-footed parents, and obtains the results reported in the table. Phenotype hyper silky fur, short-footed short-footed silky fur, hyper silky fur short-footed, hyper silky fur, short-footed, hyper wild type Place the genes in the correct order in the chromosome.

Suppose a geneticist is using a three-point test cross to map three linked rabbit morphology and behavioral mutations called si, It, and Le. The gene si is associated with the silky fur phenotype, and It is associated with the long-tailed phenotype. Both si and It are recessive mutations with respect to wild type. Le is a dominant mutation that confers the lethargic phenotype. The geneticist first crosses true-breeding lethargic rabbits to true-breeding silky fur, long-tailed rabbits. Next, the geneticist backcrosses the Fj progeny to the silky fur, long-tailed parents, and obtains the results reported in the table.
