The gene (cv) is recessive and is known to be 13.7 Map units from the beginning of the chromosome. The recessive gene (f) is 51.7 map units from the beginning of the chromosome. After doing all of the calculations i found my gene order to be we-cv-f. Gene (we) is the unknown gene which i mapped to be 17.2 map units from gene(cv). This puts the unknown gene off of the chromosome by 3.5 map units.

Why is this? What are some possible genetic explanations for this?

Please assume all calculations are correct and when this experiment was performed around 400 fly's phenotypes were scored.

Method to use to check whether gene has been knocked out : If you are asking which method to use to check whether the gene has been knocked out or not. This can be done by using gene expression. To know which method is used to generate a knockout mouse, it is RNAi also called RNA interference.
Reaction mixture contains one microgram of enzyme : Find kcat for a reaction in which Vmax is 4 x 10^-4 mol•min-1 and the reaction mixture contains one microgram of enzyme (the molecular weight of the enzyme is 200,000 D).

What are the subunits and functions of carbohydrates : What are the subunits and functions of carbohydrates? What are monosaccharides, disaccharides, and polysaccharides? What are the subunits and functions of lipids? Why is a fat a better storage compound than starch?
What are some possible genetic explanations : The gene (cv) is recessive and is known to be 13.7 Map units from the beginning of the chromosome. The recessive gene (f) is 51.7 map units from the beginning of the chromosome.
Observed and expected double cross over frequencies : When looking at the observed and expected double cross over frequencies, what does it mean if you calculate a negative interference and what does it mean when you calculate a positive interference?
Proteins rapidly pass artificial membrane : Proteins rapidly pass artificial membrane (liposome). Amphiphatic detergent such as SDS spontaneously forms bilayer in water. Glycolipids make bilayer less permeable to small water soluble molecules. The plasma membrane is a sorting station of inwar..
