- A true-breeding rabbit with agouti (mottled, grayish brown) fur crossed with a true-breeding rabbit with chinchilla (silver) fur produces all agouti offspring. A true-breeding chinchilla rabbit crossed with a true-breeding Himalayan rabbit (white fur with pigmented nose, ears, tail, and legs) produces all chinchilla offspring. A true-breeding Himalayan rabbit crossed with a true-breeding albino rabbit produces all Himalayan offspring. Explain the inheritance of the fur colors.Imagine you are performing a cross involving seed color in garden pea plants. What Fi offspring would you expect if you cross true-breeding parents with green seeds and yellow seeds? Yellow seed color is dominant over green. 100 percent yellow-green seeds 100 percent yellow seeds 50 percent yellow, 50 percent green seeds 25 percent green, 75 percent yellow seeds1. A cow is heterozygous for three genes (WwPp) where W-White, w-Brown, P-Polled, p-Horned. Give the phenotypic and genotypic ratio of their offspring if the cow is inter se mated. 2.A male Sahiwal (RRHH) is crossed with a female Angus (Rrhh). Where R-Red, r-Brown, H-Horned, h-polled. Give the phenotypic and genotypic ratio of their offspring.

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.8. In certain breeds of dogs, two different sets of alleles determine the color pattern. Black color is dominant and red color is recessive; solid color is dominant and white spotting is recessive. A homozygous black-and-white spotted male is crossed with a red-and-white spotted female. What is the probability of their producing a solid black puppy? Show your work.

In "Four o' Clock “plants, it's flower color is incompletely dominant. The red flowers are homozygous dominant, the white flowers are homozygous recessive, and the pink flowers are heterozygous. Show genetic crosses between the following Four O'clock parents, using the Punnett squares provided and indicate the genotypic and phenotypic % below: A. Red x white Genotypic %: Phenotypic %: B.

The allele for smooth peas (S) is dominant over the allele for wrinkled peas (s). Use this information to cross the following parents. I 1. heterozygous tall and smooth X heterozygous tall and smooth 2. heterozygous tall, wrinkled X short, wrinkled AL.3. In cats, agouti coat (uneven colored fur) is dominant to a solid coat. Brown coat color is dominant to chocolate color coat. Solid brown fur Agouti fur Solid fur Chocolate colored fur pattern pattern An agouti cat http://www.eurocatfancy.de/en1/nav/cat-genetics/dominance_of_genes.html Cross a cat that is heterozygous agouti and chocolate colored with a cat with a solid coat and is heterozygous brown. a. What percentage of the offspring is agouti and brown? b. What percentage of the offspring is solid and chocolate?3. In radishes, flower color may be red, purple or white. The edible portion of the radish may be long or oval. When only flower color is studied, red X white yields all purple. If these F, purples are interbred, no dominance is evident, and the F₂ generation consists of 14 red: 2 purple: 4 white. Regarding radish shape, long is dominant to oval in a normal Mendelian fashion. Determine the F, and F₂ phenotypes from a cross between a true breeding red long radish and one that is white oval. Be sure to define all gene symbols initially.
