Dihybrid A pea plant is heterozygous for seed shape and homozygous dominant for seed color. It was crossed with a plant with the same traits. R is the allele for round seed; r is the allele for wrinkled seed. y is the allele for green seed color. Solve the following: GR: PR: Probability:
Dominant and recessive alleles of a gene in garden peas, G and g, cause seeds to be yellow and green, respectively. Dominant and recessive alleles, F and f, of another gene cause seeds to be spotted or not with violet color, respectively. A plant of genotype GGFF is crossed with a plant of genotype ggff, and the F1 are allowed to self-fertilize. The phenotypes and numbers of F2 progeny are shown below: Phenotype of F2 Number yellow, spotted 89 green, spotted 31 yellow, not spotted 29 green, not spotted 11 Are the G,g and F,f genes linked?
You have a purple-flowered pea plant, but you do not know if it is homozygous (PP) or heterozygous (Pp) for flower color because both genotypes result in the same purple phenotype. Purple color allel (P) is dominant over white flower allel (p). What would you do to determine the genotype of flower color of this plant? Lötfen birini seçin: O a. Crossing the plant with homozygous large flowered pea plant (LL) Ob.

Fruit fly body color is wild type (meaning normal) Gray = B+ and black = b Fruit fly wing type is wild type normal wings = vg+ and vg = vestigial A fly which was heterozygous for both traits was crossed with a fly that was recessive for both traits. Write the genotype and phenotype that would be expected from this cross. Write the genotype and phenotype percentages that would be expected from this cross.
The diagram shows a plant that is heterozygous for two genes. G = yellow; g = green; R = round; r = wrinkled G Four different types of gametes are produced by a heterozygous individual when crossing over occurs, and two different types of gametes are produced when crossing over does not occur. What does this information reveal about crossng over? O Crossing over introduces variety by producing different combinations of alleles. O Crossing over reduces the incidence of DNA and chromosomal mutations. O Crossing over introduces variety in by creating types of genes. O Crossing over maintains the count of genes and the original alleles in both chromosomes.

Figure shows a dihybrid cross but it can be analyzed as a monohybrid cross of just smooth seed coat (S) and wrinkled seed coat (s) with complete dominance that should show a 1:2:1 ratio. Examine Figure and see if you can find these results. Likewise, it can be analyzed as a monohybrid cross of yellow seed coat versus green. Can you find these in the expected ratio?
A horticulturist runs a test cross with an offspring (F1 generation) purple plant from Question 8. The phenotypic frequencies of the resulting offspring are 50% white and 50% purple. What is the true genotype of this offspring (F1 generation) purple plant?
Given the following information, determine the inheritance of flower color in this plant and determine the genotypes of the parental individuals, which are from pure- breeding lines. CROSS 1 CROSS 2 purple X colorless all purple 9/16 purple colorless X red all purple as in Cross 1 F1 F1 F2 F2 3/16 red 4/16 colorless
A pea plant is heterozygous for both pod shape and color. I is the allele for dominant, inflated pod; i is the allele for recessive, constricted pod. G is the allele for dominant, green pod; g is the allele for recessive, yellow color characteristic. Suppose this plant is crossed with a homozygous pea with inflated, green pod, what will be the possible genotype of the offspring? Construct the punnet square, then identify the following: 1. Parents’ genes?2. Parents’ traits?3. Genes (genotype)?4. Shape, color? (phenotype)?5. Genotypic ratio?6. Phenotypic ratio?
Imagine you are crossing two plants that have these two genotypes—Tt and tt. What are the two genotypes of the gametes that the Tt plant can make? What is the one genotype of the gametes that the tt plant can make? Set up a Punnett square to analyze the cross. Does the Punnett square need to have four boxes or just two? If you were crossing a TT plant with a tt plant, how many boxes would be necessary in a Punnett square?
Hannah (with 2 n's) decided to expand on Ana's work by fencing a well isolated plot and deliberately planted 25 red plants and 25 pink plants to allow them to randomly cross. In the F1 generation she observed 115 red, 73 purple and 12 white flowered plants. Do a Chi square test to see if this is expected by random mating with a significance level of P< 0.05. Show your work including calculations, the table, the Chi square value, the degrees of freedom used, and your conclusion.
Crosses between white and red flowered plants may result in pink flowered offspring. When a pink flowered plant is crossed with a red flowered plant the phenotypic ratio of their offspring would be O 2 white : 2 red 2 red : 2 pink O1 white : 2 pink : 1 red O1 white : 2 red : 1 pink 2 pink : 2 white
