Mendel crossed Parental true-breeding (homozygous) Purple flowered peas with true-breeding (homozygous) White flowered peas, and all the F1 offspring were Purple flowered. What was the phenotype and genotype of the F1 hybrids? 3/4 purple, PP: 1/4white pp 1/2 purple: PP. 1/2 white pp purple, P Purple: Pp

Mendel crossed true breeding pea plants. One parent had round, green, seeds, and the other had wrinkled, yellow seed. All F, plants had seeds that were round and yellow. Predict the results of F2 plants, using a Punnet square or tree diagram. a. What are the results as a ratio? A What are the results as fractions?

A purple flowering, smooth seed dihybrid plant (genotype PpSs) is test crossed with a white flowering, wrinkled seed plant (genotype ppss). These produce progeny in the following numbers of four phenotypes: 24:76:74:26 (purple flower + smooth seed coat: purple flower + wrinkled seed coat: white flower + smooth seed coat: white flower + wrinkled seed coat).   a) What is the genotype of the original dihybrid plant? Specify which alleles are on each chromosome of the purple flowering, smooth seed plant (i.e. AB/ab or Ab/aB).   b) How many map units separate the colour and seed coat genes? Show your calculations.

When Mendel crossed in his P generation a yellow-seeded and green-seeded pea plants, all the offspring were yellow seeded. When he took these F1 yellow-seeded plants and crossed them with the original yellow-seeded plant from the P generation, what genotypic ratio was expected? Group of answer choices 1:2:1 3:1 1:1:1:1 1:1

In one of his experiments, Mendel crossed homozygous yellow plants with homozygous green plants. The resulting F1 generation was allowed to self-fertilize. The F2 generation produced 930 yellow seeds and 305 green seeds. What are the genotypes of this F2 generation? O YY : yy O Yy : yy O Yy: yy O YY: Yy : yy

A is dominant over a and B is dominant over b. Genes A/a and B/b assort independently. The parental cross (P) is between true- breeding (homozygous) strains (AA bb x aa BB). The resulting F1 offspring would be [Select ] A F1 x F1 cross gives the F2 generation. The ratio of phenotypes in the F2 generation can be described as [ Select ] In the phenotypic ratio, what number refers to individuals that are: dominant for both traits? [ Select ] recessive for both traits? [Select ] To what phenotypes do the "3"s in the ratio refer? [ Select ] > >

Mendel examined two distinct flower phenotypes in his pea plants. Flower color and flower position. The violet color (W) is dominant over the white color (w), and the axial position (T) is dominant over terminal (t). Predict the F1 ratios of these phenotypes from a parent heterozygous for both traits and the other parent homozygous recessive for both traits. Show your work. Flower color Flower position violet/white axial/terminal

A heterozygous green (Gg) tall (Tt) plant is crossed with a heterozygous green (Gg) tall (Tt) plant. Calculate the possible genetic outcomes.

If a red color flower (R) crosses with a blue flower (b), the result is purple flower (Rb). If the first generation is self crossed what will be phenotype in F2 generation?

# of Green Leaves _________111______________ # of White Leaves ___________35______________ 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 and give the expected ratio)
