400cM is the map size because of 8 cross over causes minimum 50cM seperation between two genes then it shows 50% recombination frequency which is maximum in the chromosome so this is the map size.

Drosophila melanogaster, the fruit fly, has a 2n chromosome number of 8 (4 chromosomes – 3 autosomes and 1 sex chromosome). Assume that you are microscopically examining the mitotic and meiotic cells of this organism. You note that in the female, two chromosomal pairs are metacentric and two pairs are acrocentric. Draw the chromosomal configurations as you would expect to see them at the stages listed: i. mitotic metaphase ii. primary oocyte (meiotic metaphase I) iii. secondary oocyte (meiotic metaphase...

An example of linked genes in Drosophila The genes for wing shape and body color are linked (they are on the same chromosome) Drosophila and linked genes In the example shown left, wild type alleles are dominant and are given an upper case symbol of the mutant phenotype (Cu or Eb). This notation used for Drosophila departs from the convention of using the dominant gene to provide the symbol. This is necessary...

In a set of replicate D. melanogaster populations of size 50 established in your lab, you observe 70 A1 alleles and 30 A2 alleles at a locus involved in wing shape. If drift is the only force operating on this population: a) What is the probability of having only 4 A1 alleles in the next generation in any of your populations? b) What is the probability that the A2 allele will be eventually fixed in the population? c) What is...

Practice Problem 72 The fruit fly Drosophila melanogaster has a haploid chromosome number of n 4, and 2n 8. Chromosome IV in this species is a tiny autosome. Flies trisomic for chromosome IV are fertile and have no apparent defects The eyeless (ey) and gawky (gw) loci are tightly linked on chromosome I Loss-of-function ey and gw alleles are recessive to ey and gw, respectively. Flies homozygous for ey lack eyes, and flies homozygous for gw have disrupted circadian rhythms....
