Get the genotypic and phenotypic ratio of the following: Dihybrid cross: Harry has 1 pair of dog, he's going to breed his Pure black, furry male to his white furless female (P generation). Also, he wants to find out what will be the result if he breed 2 offspring from F1 generation. Help him to predict the P and G ratio of F1 and F2 generation using the Punnett Square.

Pea PlantsIn pea plants, a round-seed shape (R) is dominant over a wrinkled-seed shape (r). A round-seeded pea plant was crossed with another round-seeded pea plant. What are the genotype(s) and phenotype(s) ratios of the F1 generation? Show all possibilities using Punnett squares. State the F1 generation genotypes and phenotypes.
In radishes, two incompletely dominant genes control color and shape. Red ( R) is dominant over white ( r), and heterozygotes are purple. Long (L) is dominant over round ( 1), and heterozygotes are oval. If a true-breeding long, red radish is crossed with a purple oval radish, give the F1 phenotypes and their percentages. O a. 25% long red, 50% long purple, 25% oval white O b. All long red O c. 25% oval red, 25% oval purple, 50% round purple O d.25% long red, 50% round purple, 25% round white O e. 25% long red, 25% long purple, 25% oval red, 25% oval purple
In Japanese four o'clock plants red (R) color is incompletely dominant over white (r) flowers, and the heterogynous condition (Rr) results in plants with pink flowers. Construct a punnett square and give phenotypic and genotype ratios of the offspring for the following cross a red plant and a white plant

Fur color is codominant in cows. A roan cow has a fur color of orange and white. What are the phenotype and genotypic ratios expected if a roan male and a roan female breed together?
In certain lizards, scaly skin is dominant to smooth skin and speckled color is dominant to grey color. These traits are inherited according to traditional Mendelian genetics (no linkage). The total progeny for a breeding pair of lizards resulted in the offspring listed below. What are the genotypes of the male and female parents? 102 scaly skinned, speckled off spring 110 smooth skinned, speckled offspring 38 scaly skinned, grey offspring 32 smooth skinned, grey offspring
A farmer crossed a tall (T) pea plant carrying yellow seeds and a dwarf pea plant (t) carrying green seeds . Tall is dominant over the dwarf and yellow is dominant over the green. Fertilization of the first generation pea plants produced a total of 16 second filial generation offsprings of the pea plants. How many tall pea plants that will have green seeds can you expect to be produced? What will be the genotype of these plants (Homozygous? Heterozygous? Or Both?).
In man, assume that spotted skin (S) is dominant over non-spotted skin (s) and that wooly hair (W) is dominant over non-wooly hair (w). Cross a marriage between a heterozygous spotted, non-wooly man with a heterozygous wooly-haired, non-spotted woman. Give genotypic and phenotypic ratios of offspring. In horses, black is dependent upon a dominant gene, B, and chestnut upon its recessive allele, b. The trotting gait is due to a dominant gene, T, the pacing gait to its recessive allele, t. If a homozygous black pacer is mated to a homozygous chestnut trotter, what will be the appearance of the F1 generation?
Feather colour in parakeets is controlled by two genes. Blue colour (B) is dominant over absence of colour (b). Yellow colour (Y) is dominant over absence of colour (y). When a B allele and a Y allele are present, a green parakeet is produced. What is the percent probability of obtaining a yellow or blue parakeet when a heterozygous green parakeet is crossed with a white parakeet? Show all work including Punnett square and explanation. Record your answer as a whole number rounded to one decimal place.
If a heterozygous F1 Tobacco plant was crossed to an albino plant, what is the expected number of green and white plants in the next generation? (show Punnett square) A woman homozygous dominant for albinism marries a man who is homozygous recessive for albinism. What are the possible genotypes and phenotypes percentages for their offspring? A man that can roll his tongue is heterozygous for the trait marries a woman that cannot roll her tongue. They have a child. The rolling tongue is dominant to not rolling tongue. What is the man’s genotype for tongue rolling? The women? Show the Punnett square for the child’s genotype Give the probability (percent chance) that the child can or cannot roll their tongue. Oh no! The F1 and F2 generation seed packet labels were mixed around. How would we know which seeds we planted by observing the color of the leaves? (Hint: What are the genotypes of the two generations? What color leaves do they produce in what ratios?)
Cows have codominance inheritance rules for their coat color. Cows with the genotype BB are completely black, those with the genotype WW are completely white, and with genotype BW have black and white spots across their body. Draw a Punnett Square that shows the genotypes and phenotypes of the offspring from a heterozygous coated cow and a homozygous white coated cow? Indicate also the genotypic and phenotypic % below:\
In watermelons, the green colour gene (G) is dominant over the striped colour gene (g), and round shape (R) is dominant over long shape (r). A heterozygous round green colour (GgRr) watermelon plant is crossed with another heterozygous round green colour (GgRr) plant. Determine the expected phenotypic ratio of the F1 generation.
