A geneticist is investigating the inheritance of flower color in a population of plants. According to Mendelian genetics, the expected phenotypic ratio for a dihybrid cross is 9:3:3:1 (9 individuals with PT1, 3 with PT2, 3 with PT3, and 1 with PT4). After conducting a dihybrid cross, the geneticist observed the following results: PT= Phenotype PT1: 210 individuals PT2: 70 individuals PT3: 80 individuals PT4: 40 individuals Calculate the chi-square value to determine if the observed phenotypic distribution deviates significantly from the expected ratio.

The next two questions are based on the following information. You conduct a series of two-point mapping crosses involving five genes located on Drosophila chromosome III and obtain the following percentage of recombinantoffspring:   Genes percentage of recombinant curly-yellow 23.5% lobe-curly 9% lobe-yellow 14.5% white-lobe 18.5% white-curly 9.5% white-yellow 33% bar-yellow 6.8% bar-curly 16.7% bar-lobe 7.7% bar-white 26.2% Considering that white is near the end of chromosome III, construct a map of these genes. white—–(a cM)——–A——(b cM)——-B——–(d cM)———-C——(e cM)——D The Genes A, B, C and D are

Assume that two genes are 80 map units apart on chromosome II of Drosophila and that a cross is made between a doubly heterozygous female and a homozygous recessive male. What percent recombination would be expected in the offspring of this type of cross?
