In sweet pea plant, an allele for purple flowers (P) is dominant when paired with a recessive allele for red flowers (p). An allele for long pollen grains (L) is dominant when paired with a recessive allele for round pollen grain (l). Bateson and Punnett crossed a plant having purple flowers/long pollen grains with one having white/flowers/round pollen grains. All F1 offspring had purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple flowers/round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?
Given the following testcross data for corn in which the genes for fine stripe (f), bronze aleurone (bz) and knotted leaf (Kn) are involved: Phenotype Number Kn + + 451 Kn f + 134 + + + 97 + f bz 436 Kn + bz 18 + + bz 119 + f + 24 Kn f bz 86 Total: 1,365 Determine the sequence (order) of the three genes and the calculate the distance between them.
In a diploid plant species, an F1 with the genotype Mm Rr Ss is test crossed to a pure breeding recessive plant with the genotype mm rr ss.

The first thing I suggest in attacking this problem is to use the typical convention of upper case letters for dominant alleles and lower case letters for recessive alleles as follows: F = wild type, f = fine stripe; B = wild type, b = bronze aleurone K = wild type, k = knotted leaf Then we can rewrite the phenotypes in a “language” that is more easily understood: PhenotypeNumber k F B451 k f B134 K F B97 K f b436 k F b18 K F b119 K f B24 k f b86 Total:1,365 a) Determine the sequence (order) of the…
Consider these two crosses and assume that independent segregation is exhibited by all gene pairs: RrmmTT x RRMmTtFfGg x FfGg Derive the gametic ratio of the second parent in each cross using the branching method. What proportion of the offspring in each cross will be heterozygous for all gene pairs? Derive the genotypic ratio for the offspring from each cross using the branching method. Show complete solutions.
Table 2 below shows the banding pattern for a cross between parents P1 and P2 producing the 6 progeny I1-6. The parents are double heterozygotes for two independently assorting genes. Identify the pairs of bands that correspond to the two segregating pairs of alleles. Assuming independent assortment, what is the probability that an offspring shows the pattern observed in I5.

An aquatic arthropod called a cyclops has antennae that are either smooth or barbed. The allele for barbed (B) is dominant over smooth (b). In the same organism, allele for non-resistance (N) to pesticides is dominant over resistance (n) to pesticide. What is the genotypic ratio of the offspring from a cross of Bbnn and bbNn cyclops? What would be the resulting phenotypic ratio if cyclops with genotypes BBnn x Bbnn mated?
When predicting the phenotypic ratio of a crossing between two heterozygous fruit flies, the ratio was shown to be 9:3:3:1.

In corn, purple kernels (P) are dominant over yellow kernels (p) and round kernels (R) are dominant to wrinkled kernels (r). In a cross of PpRr (purple, round) with a pprr (yellow, wrinkled) plant, the following progeny were observed: Phenotype Observed Expected (O-E) (O-E)2/E Purple, Round 117 Yellow, Round 126 Purple, Wrinkled 130 Yellow, Wrinkled 127 Total=500 Fill out the expected values in the chart above and calculate the Chi-Square value for your table, look up the p value associated with the Chi-Square. How many degrees of freedom are there in the cross? What is the Chi-Square value? What is the p-value for this cross and what does your value mean? Explain the p-value clearly.
