need help with question 3 for coincidence and interferenceHomework Answers
Answer 3:
Following Q2, we have genes in the order DPE. Distance between genes D and P = 3 m.u.
Distance between genes P and E = 18.5 m.u
We need to calculate coincidence, C and interference, I.
Interference can be calculated as :
Observed DCO = (2+3) = 5
Expected DCO
= (0.03 × 0.185 × 1000)
= 5.55
Thus,
Negative interference means that observed double crossovers (DCO) is more than expected DCO.
Since, C = 1- I, we get, C
= 1-(-0.08)
= 1+0.08
=+1.08
Hence,
C = 1.08
I = -0. 08

In Drosophila (fruit flies) the genes how, dumpy and ebony are located on chromosome 3. LOF = loss of function. Flies homozygous for a LOF mutation (no gene product made) in ebony have dark black bodies. Flies homozygous for a LOF mutation (no gene product made) in dumpy have truncated (short) wings. Flies homozygous for a partial LOF mutation (some gene product made but significantly less than normal) in how have wings that will not fold down (held out wings;...

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. The allele cn of a third gene gives cinnabar eyes, and cn+ gives red, the wild-type phenotype. A female heterozygous for these three genes is testcrossed, and 1000 progeny are classified as follows: 5 wild type;...

1. Wild type blue-eyed mary has blue flowers. Two genes control the pathway that makes the blue pigment: The product of gene W turns a white precursor into magenta pigment. The product of gene M turns the magenta pigment into blue pigment. Each gene has a recessive loss-of-function allele: w and m, respectively. A double heterozygote (Ww Mm) is self-pollinated. What proportion...
