Waxy endosperm (wx), shrunken endosperm (sh), and yellow seedling (y) are encoded by three recessive genes in corn that are linked on chromosome. A corn plant homozygous for all three dominant alleles is crossed with a plant homozygous for all the recessive alleles. The resulting Fi are then testerossed with a plant homozygous for the recessive genes. The progeny of the testcross are given below: wx sh 18 y 15 350 Wx sh y 359 sh 155 wx y 149 WX 32 sh y 39 (a) Using proper nomenclature, determine the genotypes of the P and Fi generation. i Determine order of these genes on the chromosome. 4i) What is the gene configuration of the F1 heterozygous? Construct a genetic map showing the distances between these genes.

Answer bi and bii

Waxy endosperm (wx), shrunken endosperm (sh), and yellow seedling (y) are encoded by three recessive genes in corn that are linked on chromosome. A corn plant homozygous for all three dominant alleles is crossed with a plant homozygous for all the recessive alleles. The resulting F, are then testerossed with a plant homozygous for the recessive genes. The progeny of the testcross are given below: wx sh 18 + y 15 350 WX sh y 359 sh 155 wx + y 149 WX 32 sh y 39 (a) Using proper nomenclature, determine the genotypes of the P and Fi generation. a il Determine order of these genes on the chromosome. 4i) What is the gene configuration of the F1 heterozygous? Construct a genetic map showing the distances between these genes.
