    Recombination frequency can not exceed more than 50% and after 20 map units recombination frequency decreases with each additional map unit it won't be 60 map units for 60% coz it won't reach to that level

    Ma'am this video is amazing for clearing my doubts, but I'm still confused with how to find the order of the genes , like what are the points we must focus on to find the order of the genes ? And on the last part of finding the order of the genes based on interpreting the given measurements of distances between each gene, you asked us to consider the one which only has least distance between 2 genes, I did not understand this, may you please explain to me why ?

  • @Nongthoi9344
    @Nongthoi9344 หลายเดือนก่อน

    Those who are saying that how she changed AbC to Abc and aBc to aBC -
    *Actually both the questions are different. In the first question the gene order is ABC whereas in the second question it is BAC.*
    *Therefore double crossing over in case of BAC and bac would result in BaC (or aBC) and bAc (or Abc).*
    However she forgot to change the sentence - "crossing over between B and C" to "crossing over between A and C" in the second question.
    Since crossing over is not possible between B and C in case of BAC.

    • @debishabiswas4858

    You have mentioned that if recombination frequency is 60%, then map distance will be 60 MU. But 60% recombination frequency is never possible.
    and btw, nice explanation, I've prepared so many topics for CSIR-NET from your vedios. Thanks!

      She has explained it wrong
      Although the distance is 60cM the recomb freq will be still 50%
      After all its the whole dilemma between crossing over and independent assortment 😅

    The genetic map for three genes A, B and C is as
    follows: A‐B = 10 map units, B‐C = 5 map units and
    A‐C = 15 map units. In an individual of genotype
    AbC/aBc, the percentage of gametes expected to
    be Abc is (assume no interference)
    1. 0.25
    2. 0.5
    3. 2.5

    Could you please help me out in solving one more problem please.
    In an experiment involving mapping of 3 genes (a, b and c) in Drosophila, a threepoint test cross is carried out. The parental cross was AAbbCC x aaBBcc. Thegenotypes of the double crossovers are: Aabbcc and aaBbCc. Based on this,determine the order of the genes.

    • @priyankaguleria9518
      @priyankaguleria9518 3 ปีที่แล้ว

      Gene order is ACb/aCB (confirm it by making double cross over and the answer will be the same as given the value of dco in question)

  • @laibaahmad2361

    No, that statement is not necessarily true. The concept of "double crossing over" in genetic linkage analysis doesn't imply that the lowest recombination frequency is associated with double crossovers. In fact, double crossovers would typically result in higher recombination frequencies.

  • @pratitkumartripathy5144

    • @sakhashree9723
      @sakhashree9723 3 ปีที่แล้ว +3

      Becoz DCO are also included in recombinant type.Suppose the gene order is ABC if we are finding distance between A and B it also include DCO giving gametes AbC,aBc when double cross occuring and Abc,aBC when SCO occurring and we are finding recombination frequency for calculating map distance !
      I think this is the justification as far I have understood!
