Answer #1

Here, the correct option is d) 32 map units.

Explanation -

Let ' R ' be the dominant allele responsible for the round seeds and let ' r ' be the corresponding recessive allele responsible for the wrinkled seeds.
Also, let ' Y ' be the dominant allele responsible for the yellow seed and let ' y ' be the corresponding recessive allele responsible for the green seed.
Let us suppose that gene for the seed shape (round and wrinkled ) and the gene for the seed colour (yellow and green) are linked
Now, the genotype of the parents = RY/RY and ry/ry
Their cross to produce F1 offsprings -

Parents: RY/RY X | Gametes: ry I ry V Ty (RY fi offsprings: RY lry (Round and yellow seed Now the Fi offering ore crossed toParents RY/oy x ry/oy J Comets: (RY) (my ry (Ry) Round 2 affopping: RY Ro rY ry ry Ryleg {rylay Rylsy /oY/ry I consenkled |

    Two true breeding strains of peas, one with yellow and round seeds and the other with green and wrinkled seeds, were crossed. All the F1plants had yellow and round seeds. When these F1 plants were test crossed to the green and wrinkled parental strain, the following offspring were obtained: 30 yellow and round; 20 green and round; 26 yellow and wrinkled; 28 green and wrinkled. A) Please diagram the crosses described above, showing genotypes for each plant, using your own...

    Mendel crossed peas having round seeds and yellow cotyledons (seed leaves) with peas having wrinkled seeds and green cotyledons. All the F1 plants had round seeds with yellow cotyledons. Based on this cross, what is the probability that an organism in the F2 generation will have round seeds and green cotyledons and NOT be true breeding? (Hint: Think carefully about what true breeding means in terms of genotype.)

    You perform a trihybrid cross: You cross true-breeding purple-flowered, round, yellow peas (PPRRYY) with true-breeding white-flowered, wrinkled, green peas (pprryy). You then cross the resulting F1 offspring together to generate an F2 generation. What is the probability of an F2 plant having white flowers and producing round, yellow peas?

    3. Yellow seeds is a dominant characteristic in pea plants. Pure breeding pea plants for yellow seeds were crossed with pure breeding pea plants for green seeds. The F1 generation all exhibited yellow seeds. An F1 plant was crossed to a green plant. Of 800 F2 plants, how many are expected to exhibit green seeds? Show work for full credit.

    A plant grown from a [round, yellow] seed is crossed with a plant grown from a [wrinkled, yellow] seed. This cross produces four progeny types in the F1: [round, yellow], [wrinkled, yellow], [round, green], and [wrinkled, green]. Use this information to deduce the genotypes of the parent plants. Here is what the question looks like if that helps: All it is asking for is the 2 parent genotypes but I'm not sure of the answer... if someone can explain and...

    In one of Mendel's experiments he crossed two rule breeding pea plants. One produces yellow and round seeds and the other produces green and wrinkled seeds. Yellow and round are dominant traits whereas green and wrinkled are recessive. We will classify yellow as ''Y'' green as ''y'' round as ''R'' and wrinkled as "r" In part A show F1 generation using punnet square. In part B show a punnet square for F2 generation from dihybrid cross. In part C by...

    A cross is made between a pea plant with round, yellow seeds (WwGg) and one with wrinkled, green seeds (wwgg). The progeny that resulted had the following traits: round, green: 82 round, yellow: 18 wrinkled, green: 10 wrinkled, yellow: 90 1. Which alleles were on which chromosome in the doubly heterozygous parent? 2. What is the distance in cM between these two genes?

    A true breeding dominant plant (colored, green) is crossed with a true breeding recessive plant (colorless, yellow). The F1’s are then intercrossed to give the following F2 results: colored,   green (C_G_) 180 colored,   yellow (C_gg) 28 colorless, green (¢¢G_) 20 colorless, yellow (¢¢gg) 188 Perform a Chi-square test to determine whether the genes are linked or unlinked. What is your X2 value?

    Part B - Deducing genotypes of crossed parents A plant grown from a [round, yellow] seed is crossed with a plant grown from a [wrinkled, yellow] seed. This cross produces four progeny types in the F [round, yellow], [wrinkled, yellow], [round, green], and [wrinkled, green]. Use this information to deduce the genotypes of the parent plants. Indicate the genotypes by dragging the correct label to the appropriate location.
