Explain why linkage measurements are more accurate for two genes that are close together than two genes that are farther apart.
Why are genes more than 50cM away from each other considered “unlinked?”
If two genes are 75cM away from each other, they are not genetically linked, so how do we even know that they are 75cM away from each other?
Homework Answers
In the linkage,if the distance is less than 50 centi morgan then they are liked because chances of crossing over is low and too much low if distance between the gene is very much less.so if the distance greater than 50 cM then they are unlinked,they shows the independent assortment of mendelian characters of inheritance,
We can find the diatance between the 2 genes by calculating the no. Of recombinants / total offspring ×100..by calculating this we can find the distance between thw gene.

Which statement explains why the recombination frequency between two genes is always less than 50%? Recombination cannot be more than 50% because chromosomes are only 50 map units in length. The genotype of the F, gametes will always be 50% parental gametes and 50% recombinant gametes. Genes with a recombination frequency near 50% are unlinked and have an equal likelihood of being inherited together or separately. F1 gametes always have 50% of their alleles from each parental...

Explain why two genes 50 or more map units apart on a genetic map can only result in a maximum of 50% recombinant gametes in two point cross. To answer this, ask yourself what percentage of recombinant gametes would result if the probability of crossing over in a tetrad involving these genes were 100%, as it would be if the two genes are 50 or more map units apart.

Which of these statements is incorrect? Syntenic genes are located on the same chromosome. Independent assortment results in recombinant chromosomes. You can reliably predict the relative genetic distance from genes’ physical distance on a chromosome. Linked genes are always syntenic. What is the relative genetic distance between two linked genes if the recombination frequency is 0.49? 0.49 cM 4.9 cM 49 cM 490 cM What statement best explains the distortion in Mendelian ratios observed by Bateson & Punnett in 1905?...
