Gene Combination Recombination Frequency G/H 15.1% G/I 7.5% H/I 22.6% Which of the following gene maps demonstrate the correct sequence of these genes?

Can someone explain why those values were chosen to be divided by the total? I thought it was the four smallest amounts, so I would have done 3+64+67++7/1600. Can someone explain why that would have been wrong

I am trying to understand how linkage works, and I am hoping someone can explain how to solve the following problem: The diagram shows the linkage maps for four genes: A, B, C, and D. Which genes are most likely to undergo recombination?  Which genes are least likely to recombine? A.) A and D B.) C and D C.) B and C

What does a recombination frequency of 50 indicate?

The Pipsy (P) gene can be found on chromosome 6 alongside 3 other genes D, G and T. Based on the recombination frequencies shown below, construct a chromosome map. Please indicate your answer in the following format: ABCD (where the genes are laid out on the chromosome as ABCD).  P-D: 5 G-T: 25 D-T: 13 D-G: 12 G-P: 17

Recombination frequencies have been determined between four genes (A, B, C and D) as follows: A-B: 20%, B-C:  50%, A-D: 50%, C-D: 5% Which of the four genes is/are likely linked on the same chromosome?

An individual that is heterozygous for an inversion has the following chromosomes(∗ is the centromere):M N O  P  Q  • R  S  T  Um  n  o t   s  r  • q  p  u  Assume that a crossover occurred between P and Q.  Starting with “M” allele, list the remaining genes in order (NO spaces between the letters) of the chromosome resulting from crossing over. You must use upper and lower-case letters correctly and the * symbol for the centromere(s).

Researchers have discovered that some regions of chromosomes are more likely than others to cross over, these areas of frequent crossing over are called "recombination hot spots". Gene A and B are 500,000 bp apart - the genes are either side of a recombination hot spot. Gene C and D are also 500,000 bp apart but the region containing genes C and D are not near a recombination hot spot. Would the map distance between A and B be the same as the map distance between C and D? Explain your answer.

Create a chromosome map for each set of three genes from the given information. b) the crossover frequency between gene X and gene Z is 8.5 %, the crossover frequency between gene Y and gene Z is 2.25 % and between gene Y and gene X is 6.25 %

Are two genes linked if not linked to the same marker on a chromosome.? Let's say we want to figure out whether two genes are linked on a particular chromosome so we cross-test them to a marker gene on that chromosome. Gene A is found to have an approximate 50% recombinant frequency so we say it's not linked to the marker. The other gene B however is found to have 40% recombinant frequency with our marker so we say it's linked. Now the question is are the two Genes A and B linked or not? Please explain your reasoning.
