The following table provides results (petal colour) of 4 different F1 X F1 crosses. The genes involved in the 4 crosses are unrelated. Complete the table by indicating the phenotype of the testers and what would be the phenotypic ratios if the each F1 (indicated in the F1 phenotype column) were testcrossed.

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 offspring genotypes are as follows: Genotype Number Mm Rr Ss 687 Mm Rr ss 5 Mm rr Ss 68 Mm rr ss 196 mm Rr Ss 185 mm Rr ss 72 mm rr Ss 8 mm rr ss 679 Total 1900 1. What is the interference value for this data set?
Three linked loci are evaluated to determine the recombination frequency of the loci. To set up the test cross, an individual that is true breeding dominant for all three phenotypes is crossed with an individual that is true breeding recessive for all three phenotypes. F1 offspring are crossed with individuals that are recessive for all phenotypes. The phenotypic results are shown in the table below. Phenotype Number of Offspring Dominant 1, Dominant 2, Dominant 3 322 Dominant 1, Dominant 2, Recessive 3 82 Recessive 1, Dominant 2, Recessive 3 5 Dominant 1, Recessive 2, Dominant 3 2 Recessive 1, Dominant 2, Dominant 3 28 Recessive 1, Recessive 2, Dominant 3 89 Recessive 1, Recessive 2, Recessive 3 312 Dominant 1, Recessive 2, Recessive 3 25 1.

A series of three-point testcrosses is made to determine the genetic map order of seven linked allele pairs: A/a, B/b, G/g, H/h, Q/q, R/r, and Y/y.From each cross between a triply heterozygous parent listed below, two recombinant classes were noticed as the least frequent among all 8 progeny classes, and are listed at the right in the table. A. For each testcross write the genotype of the F1 heterozygous parent.

Why is the recombination frequency for the outside pair of genes not equal to the sum of the recombination between the adjacent gene pairs?
The F1 from a cross of AABB x aabb is testcrossed, resulting in the following phenotypic ratios: AB 308 Ab 190 ab 292 aB 210 (1) what are the genotypes for the listed phenotypes? (2) why aren't the phenotypes in a 1:1:1:1 ratio? (3) what is the frequency of recombination between genes A and B?
A cross was made between a plant that has blue flowers and purple seeds and a plant with white flowers and green seeds. The F1 generation was then allowed to self-fertilize. The following data were obtained. F1 Generation: All offspring have blue flowers with purple seeds. F2 Generation: 208 blue flowers, purple seeds 13 blue flowers, green seeds 19 White flowers, purple seeds 60 white flowers, green seeds Total: 300 The scientist needs to test if the two genes segregate independently and has formulated the null-hypothesis that there is no significant difference between the observed and expected data. What are the degrees of freedom for this experiment?
