Question

Map distance of genes on chromosome is calculated by

Answer 1

Answer:

hey here is your answer

Linkage map units don't actually correspond to a specific length of chromosome. The exact distance calculated between two genes depends upon how much information you have about what's going on in the region between the genes. ... We we'd calculate the distance between B and C as: (290/1700) x 100 - 17.1 LMU.

hope it help you ☺️

Answer 2

Answer:

Map distance of genes on chromosome is calculated by recombination frequency of each gene locus.

Explanation:

• A visual representation of the relative distances between the genes in a linkage group is a chromosomal map, also called a linkage map. These distances, which are stated as a percentage of crossing over, are shown for a single group of chromosomes.
• The unit of measurement for this distance is the map unit, which is arbitrary. It refers to how distantly related genes are from one another.
• The linear distance that one percent of the population traverses over is represented by one map unit.
• A map unit is equivalent to 1% of a crossing over.
• Therefore, in order to calculate the map distance of genes on a chromosome, we need to know the recombination frequency, or the proportion of each gene locus that crosses over.
