A heterozygous trihybrid corn plant is test crossed and the following progeny are oduced. The mutant traits-booster (b), silkless (s), liguleless (1) - are recessive to er wild-type (+) alternatives. (Hint: The wild-type alternatives (+) for each of the three mutant traits can be named B, S, and L, respectively.) (6 points) Note: This is a three point cross. Show all your work to get full credit. You will get partial credit for any work that is correct even if...

By analyzing the gametes from a trihybrid fruit fly that is heterozygous for three linked genes (AaBbDd), you obtain the following data: Organize the 8 haploid genotypes into pairs that correspond to parentals, double crossovers (DCO) and each of the two types of single crossovers (SCO). Draw a map showing the order of the three genes on the chromosome. Label the map to indicate the distances (in centimorgans or map-units) between the gene in the middle and the genes on...

Question 5 (14 marks) The allele cn gives fruit flies cinnabar eyes, whereas the allele cn gives red, the wild-type phenotype. The allele wx of a separate allele gives waxy wings, and wx gives non-waxy wings (wild-type). The allele b of a third gene gives fruit flies a black body, whereas the allele b gives a brown (wild-type) body colour. A geneticist knows these three genes are on the same chromosome, but does not know what order the genes are...

Mapping genes with recombination frequencies in Drosopna 1. Suppose you know of three linked loci on the Drosophila X chromosome (a, b, and c). Assume that you are starting out with true-breeding stocks that show all three recessive traits and true-breeding stocks that show all three dominant traits. A. If you wanted to do a 3-point test cross to map the three loci, how would you set up the cross? What genotypes do you use for males and females in...

The results for the F2 progeny are shown for a F1 cross using
the two X-linked markers:
w+ and m+.
As shown in the figure, the F1 cross is between the following
two parents:
- a phenotypically wild-type (red eye, full wing), heterozygous
female: w+m+/wm
- a double mutant male (white eye, miniature wing):
wm/Y
Answer the following questions:
1) In the F1 cross, can you infer the genotype for the phenotype
in the female? Why or why not?
2)...

You have three genes on the same chromosome - A, B and C. Each gene has two alleles in a dominant/recessive relationship. For these genes the homozygous recessive has the mutant phenotype for that trait, the dominant phenotype = wild type for that trait. allele A is dominant to a; phenotype a = mutant for trait a; phenotype A = wild type for trait A allele B is dominant to b; phenotype b = mutant for trait b; phenotype B...

Can you please help me with this problem:
3. The allele b gives Drosophila flies a black body, and b+ gives brown, the wild type phenotype. The allele wx of a separate gene gives waxy wings, and wx+ gives nonwaxy, the wild type phenotype.

A female heterozygous for these three genes is testcrossed, and 1000 progeny are classified as follows: 5 wild type;...
