The expected results of Bateson and Punnett’s cross of F 1 plants. Introduction: Bateson and Punnett in the year 1911 conducted an experiment on sweet peas. They made a cross of sweet peas showing linkage between two different genes. In their study they took into consideration two traits- the flower color and pollen shape.

Assignment 3 Linkage and Recombination 1. In corn, the genes an (anther ear), br (brachytic), and f (fine stripe) are linked. Testeross data are as follows: Number Number 355 2 Progeny Progeny +++ 88 an ++ ++f + br + + br f 21 an +f an br + an br f 2 17 399 55 Determine the linkage map and the genotype of the homozygous parents used to obtain the heterozygote for testcross.

What is the order of genes on the chromosome?22. In the tubular flowers of foxgloves, wild-typecoloration is red while a mutation called whiteproduces white flowers. Another mutation, calledpeloria, causes the flowers at the apex of the stemto be huge. Yet another mutation, called dwarf,affects stem length. You cross a white-floweredplant (otherwise phenotypically wild type) to aplant that is dwarf and peloria but has wild-typered flower color. All of the F1 plants are tall withwhite, normal-sized flowers. You cross an F1 plantback to the dwarf and peloria parent, and you seethe 543 progeny shown in the chart.
