In C. elegans, lon-2 and unc-2 are recessive mutations that are 8 map units apart on the X chromosome.  An hermaphrodite who is Lon and Unc is mated to a wild-type male.  An F1 hermaphrodite is mated to a wild-type male.  What are the expected percentages of the different phenotypes among the male progeny?

Explain this to me…..

Mutant female: yellow body and purple eyes.  Male: Normal Use: https://www.sciencecourseware.org/FlyLabJS/   Which mutant alleles are dominant? Which mutant alleles are recessive?   Which mutant alleles are sex-linked? Which mutant alleles are autosomal?   Can you tell at this point if the two genes are linked?   Show the results of the dihybrid analysis.  Are genes segregating independently? What is the evidence for or against this?   Show the crosses you will use to obtain the mapping data.   For the mapping crosses, Write out the crossing scheme and make a table of the results (ignore sex in this table, combine the male and female progeny). Identify the parental classes and the recombinant classes. For a 3-point cross, identify the double cross overs. Show your calculations for the recombination frequencies between the three genes (for the 3-point cross) or the two genes (for the two-point crosses).     Draw a map of the Drosophila chromosomes 2, 3, and X, including…

A diploid species has 3 pairs of chromosomes in its somatic cells. In males, the first pair is large submetacentric[1]; the second is medium acrocentric[2], and the third is small telocentric[3].  In females, the first two pairs are like those of the males while the third is large metacentric[4][5], with satellite4 Illustrate the karyograms (drawing/picture of the chromosome) of the following:   A triploid cell in females         tetrasomic cell in males         tetraploid cell in females     [1] submetacentric --centrosome is just above the middle of the chromosome  [2] acrocentric --centrosome is much higher location than submetacentric  so that the “p” arm of the chromosome is much shorter than the q arm [3] telocentric --the centromere is at the end of the chromosome [4] metacentric --centrosome is in the middle of the chromosome; thus the “p-arm” and the “q-arm” or both arms of the chromosome are equal in length [5] satellite-a constriction in an arm of a chromosome, aside…
