Describe the phenotypes and genotypes Ure 16. In watermelons, bitter fr atermelons, bitter fruit is dominant over sweet fruit, and yellow spots are dominant over no spots. ung these are independently assorted traits, a homozygous plant that produces fruit bitter with ow spots is crossed with a homozygous plant with fruit sweet and spotless. The F1 are intercrossed to produce F2. a. What are the phenotypic ratios in F2? b. If an F1 plant is backcrossed with the bitter, spotted...

In cucumbers, dull fruit (D) is dominant over glossy fruit (d), orange fruit (R) is dominant over cream fruit (r), and bitter cotyledons (B) are dominant over non-bitter cotyledons (b). The three characters are encoded by genes located on different pairs of chromosomes. A plant homozygous for dull, orange fruit and bitter cotyledons is crossed with a plant that has glossy, cream fruit and non-bitter cotyledons. The F1 are intercrossed to produce the F2. a. Give the phenotypes and their...

In dogs, short hair is dominant over long hair, and dark coat
color is dominant over albino fur. Assuming that these effects are
caused by two independently sorting genes, what will be the result
of the following cross? Create a Punnet square and show your
work.

1. In corn, purple kernels are dominant to yellow kernels, and starchy kernels are dominant to sweet kernels. If the genotypic verent crosed with a yellow, sweet parent? What would be the phenotypic ratio of the Fa complete dominance is the pattern of inheritance, what would be and phenotypic ratios for the offspring of a true breeding purple, starchy generation? 2. In guinea pigs, a cross between black furred and brown furred parents gives offspring with 100% black...

4. In summer squash, fruit color and shape are controlled by two independently assorting genes as follows: Trait Gene Alleles Phenotypes Fruit color W W w White fruit yellow fruit Fruit shape D D d Disk-shaped fruit sphere-shaped fruit A homozygous White Disk plant has been crossed with a homozygous Yellow Sphere plant (this is the P1 generation). List the expected genotype and phenotype of the F1 plants? P1 WWDD x wwdd F1 WwDd Genotype: WwDd Phenotype: White, Disk If...

1. In humans, dark hair (D) is dominant over blond hair (d). If a heterozygous dark haired man had a son with his blond haired wife, what would the probability be that the son would have dark hair like his father? 2. a) In tomatoes, red fruit (R) is dominant over yellow fruit. If a homozygous red fruit plant is crossed with a yellow fruit plant, what are the expected genotypic and phenotypic ratios of the F1 generation? b) if...

In rabbits, spotted coat (S) is dominant to solid color (s) and black (B) is dominant to brown (b). A true-breeding black spotted rabbit is mated to a true-breeding brown solid rabbit to Iproduce a heterozygous F1 generation. Two F1 individuals are mated. You see the four expected phenotypes of offspring, but not in the expected 9:3:3:1 (black spotted: black solid: brown spotted: brown solid) ratio. This tells you that o that the genes for fur pattern (spotted vs. non-spotted)...

In mice, black fur (B) is dominant over brown fur (b). Breeding a brown mouse and a homozygous black mouse produces all black offspring. a. What is the genotype of the gametes produced by the brown-furred parent? ________________________________________________________ b. What is the genotype of the brown-furred parent? ________________________________________________________ c. What is the genotype of the black furred parent? ________________________________________________________ d. What is the genotype of the black-furred offspring? By convention, P stands for the parental generation. The offspring are called...

2. The lubber grasshopper is a very large grasshopper, and is black with red and yellow stripes. Assume that red stripes are expressed from the homozygous RR genotype, yellow stripes from the homozygous rr genotype, and both from the heterozygous genotype. A. If two heterozygous grasshoppers were crossed, what would be the genotypic ratio of the F1 generation (RR:Rr:rr)? Fill in the Punnett square. B. What genotypes would be produced by crossing a grasshopper with both color stripes and one...

In cucumbers, green color (W) is dominant over yellow color (w) and spiked cucumbers (D) are dominant over smooth cucumbers (d). A cucumber plant true-breeding for green, spiked cucumbers is crossed with a plant true-breeding for yellow, smooth cucumbers. 1. What will the phenotypes and genotypes of the F1 generation be? 2. If the above F1 progeny are self-crossed, what ratio of the F2 offspring will be: WwDd wwDd WWDD wwDD 3. What ratio will have green spiked cucumbers? 4....
